Cottier Kids Clothing Review 2026: Jumpers, Skirts & Knits — Sizing and What to Buy

Last updated: September 2026

Cottier is a kids' clothing label built around one look: pleated corduroy jumpers, wool pinafores, knee-length skirts and cable-knit sweaters in mustard, crimson, charcoal and navy, sized 2 to 16 and priced $38 to $118. If you want school-photo, holiday-card or first-day-of-school clothes that look tailored rather than cute, Cottier does that better than almost any brand at this price.

The honest caveats: a Cottier "jumper" is a sleeveless dress, not a sweater; most listings name the fabric (wool, corduroy, silk, denim) but not a fiber percentage; and the signature pieces cost $118. This review walks through every Cottier line we carry, how the sizing runs (from the brand's own garment charts), what to buy first, and who should shop elsewhere.

Cottier jumpers and pinafore dresses: the pieces people search for

A Cottier jumper is a sleeveless dress worn over a turtleneck or shirt, the American meaning of the word rather than the British one. The Olivia Jumper ($118) is the pinstripe version with a front zipper and a tie at the neck, in maroon or cocoa, listed in sizes 3 to 16. The Lyla Jumper ($118) is the wool one, an A-line with side pockets and a front zipper, in crimson, charcoal or mustard.

The Delilah Dress ($78) is the corduroy pinafore: a pleated drop-waist skirt, a front zipper and an embroidered logo, in oatmilk or mustard, listed in sizes 2 to 16. It is the one to start with if $118 is more than you want to spend on a single dress, and the one most likely to survive a playground.

The front zipper is the practical reason to choose a jumper over a back-buttoned dress. A child in size 4 or 5 can get the Olivia or Lyla on and off without help, which matters on a school morning and in a preschool bathroom. The tie at the Olivia's neckline adjusts the fit at the chest, so it accommodates a growth spurt better than a fixed bodice.

Cottier dresses: Eleanor, Stella, Lyla and Aria

Cottier makes four long-sleeve dresses, and they solve four different problems. The Eleanor Dress ($118) is the navy pleated one with a white Peter Pan collar and a zipper: the dress for a school concert, a wedding or a holiday card, listed in sizes 2 to 16.

The Stella Dress ($118) is a floral-print silk with pleats and a zipper, in navy, sizes 2 to 14. It is the most formal thing Cottier makes and the one to treat as dry-clean-only until the sewn-in label says otherwise. The Lyla Dress ($118) is a printed, collared dress with a smocked front and ruffle sleeves, in a multi plaid or charcoal, sizes 2 to 14.

The Aria Dress ($78) is the everyday option: a denim shirt-dress with a tie belt, red stitching and embroidery on the back, listed in sizes 2 to 16. It is the only Cottier dress you would happily send to a birthday party at a trampoline park, and at $78 it is the best value in the dress lineup.

If you are comparing these against other brands' party dresses, our girls' Christmas and holiday dresses guide lines up twirl, smocked and velvet options from $16, and the toddler dresses guide covers the everyday cotton end.

Cottier skirts: pleated, wrap and denim

Skirts are where Cottier is deepest, and they are the cheapest way into the look. The Delilah Skirt ($62) is the pleated corduroy in mustard or oatmilk with a side zipper. The Selena Pleated Skirt ($66) is the soft gray knife-pleat with an embroidered horse, the closest thing to a uniform skirt in the line, listed in sizes 3 to 16.

The wrap skirts are the ones to buy for a child who is between sizes. The Olivia Wrap Skirt ($76) comes in emerald or maroon pinstripe with a contrast trim; the Aria Plaid Wrap Skirt ($76) is soft wool with a front button; and the Eleanor Skirt ($76) is a wool plaid wrap with a front toggle, listed in sizes 8 to 16.

Two more worth knowing: the Rae Multi Pleated Skirt ($72), a plaid with a side zipper and button in navy, red and green, and the Aria Skirt ($62), a denim A-line with red stitching, a horsebit detail and real pockets. The brand's skirt chart notes that the waist has hidden elastic, so the listed waist is a maximum and the fit is cinched rather than loose.

Cottier sweaters and cardigans

Cottier knitwear is priced at one number, $64, across the line, so the choice is about neckline and pattern rather than price. The Sean Cable Knit Sweater is the crewneck cable in navy, cranberry or mustard with a small embroidered logo, listed in sizes 2 to 16 and cut on the boys' chart. The Elliot Equestrian Sweater is the gray crewneck with a horse-and-rider intarsia on the front, and the only Cottier knit listed from 12 months.

For girls, the Cottier Chunky Knit Top has a bow at the shoulder and "Cottier" knitted into the front, in crimson, gray or navy, sizes 6 to 16. The Olivia Knit Sweater is a textured, collared knit with a back button closure in emerald or cranberry, also sizes 6 to 16. The Ashton Knit Sweater is the all-over horse intarsia in brown, sizes 2 to 10.

Cardigans: the Elliot Knit Cardigan has front buttons and elbow patches in gray, chestnut or navy; the Eleanor Cardigan is the girls' version with a scalloped edge in chestnut; and the Delilah Knit Zip Up is a lightweight collared zip cardigan in crimson or mustard. For how these stack up against other kids' knits by warmth and price, see our kids' sweaters and layers guide.

The turtleneck that goes under everything

The reason a Cottier outfit looks finished is the turtleneck underneath, and it is the least expensive thing the brand sells. The Eleanor Turtleneck ($50) is the soft long-sleeve in cocoa, gray, navy or white with a small pearlized logo at the chest, listed in sizes 2 to 16. The Delilah Turtleneck ($50) is the ribbed version in crimson, mustard or oatmilk, made to match the Delilah corduroy exactly.

Buy the turtleneck in the same size as the jumper it goes under. On the brand's chart the turtleneck and the jumper share the same chest measurement at every size, so a size 6 turtleneck sits flat under a size 6 Olivia with no bunching at the armholes. One white and one gray covers every jumper and skirt in the line.

Cottier for boys: blazers, stripe shirts and slim pants

Cottier's boys' clothes are a small, complete uniform. The Elliot Blazer ($76) is a soft wool single-breasted jacket with a button closure in navy or gray, listed in sizes 2 to 14. The Elliot Slim Stretch Pants ($60) have a criss-cross waistband and come in navy or gray; the Elliot Tartan Slim Stretch Pants ($60) add a front tab and a tartan in navy or brown.

Shirts: the Leo Stripe Shirt ($56) is a button-down with an embroidered logo in white, brown or mustard; the Elliot Stripe Shirt ($56) is the button-up in gray or navy; the Oz Micro Plaid Shirt ($54) has a round collar and front buttons; and the Dani Polo ($38) is the long-sleeve navy polo with a collar detail, and the cheapest piece in the line.

The brand's pant chart gives a size 4 inseam-to-hem length of 23.5 inches and a size 8 of 31.5 inches, with the waist growing only from 21.5 to 25 inches across those sizes. That is a slim cut: if your son is sturdy through the middle, size by waist, not by age, and expect to hem.

Sweatshirts, polos and the zip-up

For days that are not picture days, Cottier makes a handful of softer pieces. The Sammi Sweatshirt ($56) is a lightweight gray crewneck with a small horse print, listed from 12 months to size 16, one of only two Cottier pieces with baby sizes. The Dani Sweatshirt ($56) is the stone-colored crewneck with a front logo print, sizes 2 to 16.

The Selena Zip Up ($68) is a gray zip sweatshirt with a high collar, front pockets and a tie at the neckline. It is the only hooded-style piece Cottier makes, and it comes with a caution we cover in the complaints section below.

Which Cottier piece to buy: the comparison table

Prices, listed sizes and fabric notes below come from the product pages as of September 2026; sizes shown are the full size ladder each product is listed in, and individual sizes sell out. Anything a listing does not state says "see product page."

How does Cottier sizing run?

Cottier sizing runs true to size by the brand's own account, on a US ladder of 2, 3, 3X, 4, 5, 6, 6X, 7, 8, 10, 12, 14 and 16, with 12M, 18M and 24M on two boys' tops only. The 3X and 6X sizes are genuine half-steps: on the jumper chart a 3X is 1.5 inches longer than a 3 and a 6X is 1.5 inches longer than a 6, with a quarter-inch more chest, so they are the sizes to pick for a tall, slim child rather than a bigger one.

The charts on every Cottier product page are garment measurements, not body measurements, and the chest figure is the garment measured flat across the front. Double it, then compare with your child's chest measurement; if the doubled number gives less than 1 to 2 inches of room, go up. Two more chart notes worth knowing before you order: girls' tops and dresses from size 6 up come with 3/4-length sleeves by design, and skirt waists have hidden elastic, so the listed waist is the maximum.

Here is the brand's jumper and dress chart, with the boys' pant chart beside it, for the sizes most people buy:

The jump between size 6 and size 7 is the biggest on the chart: 3.5 inches of dress length in one step, against 1.5 inches everywhere else. A child who is 6X on length will often still fit a 6 in the chest, and that is exactly the case the 6X size exists for.

Fabric and care: what the listings say, and what they don't

Cottier listings name a fabric family but almost never a fiber percentage. What the product pages do state: the Lyla Jumper, Elliot Blazer, Aria Plaid Wrap Skirt and Eleanor Skirt are wool; the Delilah dress and skirt are corduroy; the Stella dress, skirt and blouse are silk; the Aria dress, shirt and skirt are denim; the Delilah Turtleneck is ribbed; the Elliot pants are stretch. The Olivia pinstripe pieces, the Eleanor plaid dress and every sweater list a pattern and a construction but not a fiber.

That gap is smaller than it looks, because two federal rules fill it on the garment itself. The Textile Fiber Products Identification rule, 16 CFR 303.16, requires the label to carry the generic fiber names and percentages by weight of every fiber at 5 percent or more, plus the country of manufacture. The Care Labeling Rule, 16 CFR 423.6, requires a care label with either a washing instruction (hand or machine, and water temperature) or a drycleaning instruction. So the fiber content and the care instructions you cannot find online will be on the sewn-in label when the piece arrives.

Until you read that label, the safe defaults are: wool jumpers, wool skirts and the blazer are dry-clean or hand-wash; the silk Stella pieces are dry-clean; corduroy and denim will take a cold machine wash inside out; and any sweater goes flat to dry. None of the listings carry a care instruction, so our table says "see product page" for care on purpose.

School uniform, holiday photos and everyday styling

Cottier is easiest to style because it was designed as a system: the Delilah Turtleneck matches the Delilah corduroy, the Eleanor Turtleneck matches the Eleanor dress and skirt, and the navy across the Sean sweater, Elliot pants and Dani Polo is the same navy. Three combinations cover most of what parents buy it for.

School uniform without the uniform supplier: the Selena Pleated Skirt or Delilah Skirt with a white or gray Eleanor Turtleneck, or the Dani Polo with Elliot Slim Stretch Pants for boys. If your school's dress code names a color rather than a supplier, navy, gray and white are all in the line.

Holiday-card photos: a Lyla Jumper in crimson on one child, the Elliot Equestrian Sweater on another, and a charcoal Lyla on a third is the exact combination in the brand's own photography, and it works because the colors sit together without repeating. Add red tights or red socks and brown shoes; leave the white turtleneck showing at the collar.

Everyday in fall: the Aria Dress or Aria Skirt over a turtleneck, with the Sammi or Dani Sweatshirt over the top on cold mornings. The denim pieces are the ones that will take a full week of school, playground and car seat without showing it.

Where to buy Cottier

EasyTot carries Cottier's jumpers, dresses, skirts, knitwear, turtlenecks and boys' tailoring in sizes 2 to 16, with fast US shipping, on the Cottier collection page. The brand's own site, shopcottier.com, describes Cottier as a children's fashion house devoted to Parisian luxury and French-inspired design, made in limited quantities, and lists independent boutiques in the US, the UK and Israel that stock it.

Because the line is produced in limited runs, individual sizes and colors go out of stock and do not always return in the same season. If a specific jumper in a specific size is the whole reason you are buying, buy it when you see it rather than waiting for a sale.

The honest complaints

Cottier is new to EasyTot and has no customer reviews on our site yet, so what follows comes from the listings, the brand's size charts and the product photography, not from parent reviews. These are the things we would want to know before spending $118.

The price. A wool jumper at $118 plus a $50 turtleneck is $168 for one outfit a child will outgrow in a year or two. The wrap skirts and 3X/6X sizes help, and the corduroy Delilah pieces bring the outfit down to $128, but this is a brand you buy for one or two statement pieces, not a full wardrobe.

The neckline tie on the Selena Zip Up. The Selena has a cord that "ties into a bow at the neckline." Under 16 CFR 1120.3, children's upper outerwear in sizes 2T to 16 with a drawstring that does not conform to ASTM F1816 is deemed a substantial product hazard. The listing does not say whether the Selena's cord is a working drawstring or a sewn-on bow, and we could not confirm which from the photos, so for a child under 12 we would choose the tie-free Delilah Knit Zip Up instead, or ask before ordering.

The logo. Most pieces carry a small "plastic pearlized logo" at the chest or hem, and some carry an embroidered one. It is discreet in the photos, but if you want a plain garment for a uniform, the Delilah Skirt, Eleanor Skirt and Elliot pants are the least-branded pieces.

No fiber content online, no care instructions online. Covered above: it is on the label, not the listing. For a $118 dress that is a real gap, and it means you cannot rule out a wool-blend allergy before ordering.

Almost no baby sizes. Only the Sammi Sweatshirt and the Elliot Equestrian Sweater are listed below size 2. If you want the same look on a baby sibling, you will be buying it elsewhere; our best baby clothing brands guide is the place to start.

How Cottier compares

The two brands EasyTot shoppers cross-shop with Cottier are not really alternatives; they answer different questions. Hope & Henry makes classic, heirloom-style sweaters, dresses and pants with most pieces between about $21 and $49, so it is the brand to buy when you want the same collared, cable-knit look at half the price, and it goes down to baby sizes. It does not make wool jumpers or silk dresses, and the pieces are cut fuller.

Lovely Littles is a print-led baby and kids' label with most pieces between about $14 and $46, strongest under age two, and the right choice for matching a baby sibling to an older child. It has no tailoring at all; our Lovely Littles review covers its two size ladders. A school-uniform supplier will beat Cottier on price for a plain pleated skirt, but not on the corduroy, the wool or the photographs.

Who should buy Cottier, and who should skip it

Buy Cottier if you have a child between size 3 and size 12, you need one or two outfits that photograph well and survive a formal occasion, and you would rather pay $78 to $118 for a jumper that lasts two seasons and passes to a sibling than $30 for one that pills by spring. The Delilah Dress, a Delilah Turtleneck and the Sean Cable Knit are the three pieces to start with.

Skip Cottier if you are dressing a baby, you need a stated fiber content before you buy, you want machine-wash-everything play clothes, or you are outfitting several children head to toe on a budget. Hope & Henry covers the first and last of those; a plain cotton dress from our toddler dresses guide covers the middle two.

Bottom line: Cottier is the best-photographed, best-tailored kids' clothing at this price that we carry, with a sizing chart honest enough to shop from and two real gaps, fiber content and baby sizes, that you should know about before you click.
