Buying Clothes in Korea When You're Not a Korean Size
Trendy Korean brands often stop at a 66 (US 6–8), and 'free size' is a US 2–6. Here's the size conversion, and where tall, plus, and wide-foot shoppers can actually buy.

Korean women's clothing is labelled 44, 55, 66, 77. The numeric system was created in 1981, and the base size "55" comes from the last digits of the average Korean woman's measurements then — 155cm tall, 85cm chest. Each step up adds roughly 5cm of height and 3cm of chest.
The problem: most trendy Korean brands don't make anything above 66 (labelled "M," but really a US 6–8), and anything marked "free size" is usually cut to a 55 or 66 — so it only covers about a US 2–6. If you're tall, above a US 10, or your feet are over 250mm, you need a strategy.
- Korean sizes run 1–2 sizes smaller than US or European ones. A Korean "L" (77) is roughly a US 8–10; an "XL" (88) is roughly a US 10–12. In a shop, grab one size up from your US size.
- "Free size" is about a US 2–6. Above that, skip the free-size shops (Dongdaemun (동대문), Instagram boutiques) — many have no fitting rooms and no returns.
- Where the bigger sizes are: the SPA brands (SPAO, 8seconds, TOP TEN, Musinsa Standard) go further than boutiques. The men's section. Plus-size online malls like 66girls. And the global brands that operate in Korea (Uniqlo, Zara, H&M, Nike) carry their full home ranges.
- Shoes: Korea sizes in millimetres. For women, above 250mm (US 8) the style choice drops off fast, and above 260mm you mostly won't find it in a regular shop. Buy large sizes before you come.
- Online beats in-store here — Musinsa and Zigzag let you filter by size and give real garment measurements.
What is my size in Korean sizing?
A rough guide for women's clothing. It varies a lot by brand, so treat it as orientation, not gospel.
| Korea (KR) | Label | US | UK | Chest |
|---|---|---|---|---|
| 44 | XS | 0–2 | 4–6 | ~82cm |
| 55 | S | 2–4 | 6–8 | ~85cm |
| 66 | M | 6–8 | 10–12 | ~88cm |
| 77 | L | 8–10 | 12–14 | ~91cm |
| 88 | XL | 10–12 | 14–16 | ~94cm |
Men's clothing uses 90/95/100/105 — the chest measurement in centimetres (95 = a 95cm chest). Because it's centimetre-based, it's more consistent than the women's system.
The real move: ignore the "M" on the label and read the measurements in centimetres. Most Korean product pages give you a table of actual garment measurements — total length, shoulder, chest, sleeve. Measure a piece you own that fits well and compare the numbers. That's more reliable than any label.
Does "free size" actually fit everyone?
No. "Free size" means the garment was made in a single set of measurements, and in 2026 that single set is almost always a 55 or a 66 — roughly a US 2–6. The Dongdaemun wholesale malls, the small boutiques in Hongdae (홍대) and Seongsu (성수), the Instagram shops — they're free-size-first, so if you're outside that range they're a waste of an afternoon. Some of these have no fitting room, or a "buy it as you see it" policy, and plenty don't do exchanges or refunds.
Where do you buy the bigger sizes?
- The SPA brands — SPAO, 8seconds, TOP TEN, Musinsa Standard. Wider size ranges than boutiques (usually to XL, sometimes XXL), big stores, fitting rooms, and returns that work. Look for the large branches in Myeongdong (명동), Hongdae, and Gangnam (강남).
- The men's section — oversized fits are the trend, so there's a lot that works as unisex. Check the men's corner of a SPA store first.
- Plus-size online malls — 66girls (separate plus and tall sections), plus specialists like Athlete Korea and Gabig (up to a Korean 4XL) and Coolsis (S–3XL). Most ship internationally.
- Global brands operating in Korea — Uniqlo, Zara, H&M, COS, the Nike and Adidas stores. Same size ranges as at home. It's not "only in Korea," but if you need something that fits today, it's the reliable option.
Why are shoes so hard?
Korea sizes shoes by foot length in millimetres too. The most common women's sizes here are 225–240mm (US 5.5–7), and shops usually stock up to about 280mm. But for women's shoes, once you pass 250mm (US 8) the style options shrink sharply, and 260mm and up is close to unfindable in a regular store.
| mm | US Women | UK |
|---|---|---|
| 230 | 6 | 3.5 |
| 240 | 7 | 4.5 |
| 250 | 8 | 5.5 |
| 260 | 9 | 6.5 |
| 270 | 10.5 | 7.5 |
If you're a larger size: the Nike, Adidas, and New Balance brand stores (the men's lines run big), or buy before you fly. Budget half a day for shoe shopping in Seoul only if your feet are 260mm or under.
Why online beats in-store
Apps like Musinsa and Zigzag let you filter by size, give you a measurement table on every product, and (on some) do free returns. Rather than trekking around shops looking for something that fits, sit in your accommodation, set the size filter, compare the centimetre measurements, and order. If you're mid-trip, you can have it delivered to your accommodation the next day.
Yuna's TipIf you're not a Korean size, don't set out to buy "Korean-style clothes" — the trendy domestic labels often stop at 66. Spend the shopping time on things that don't have a size: ceramics, skincare, stationery, homeware. You'll come home with more you actually use.
Korean women's sizes: 44 (XS) / 55 (S) / 66 (M) / 77 (L) / 88 (XL), and they run 1–2 sizes smaller than US/EU — a Korean "L" is roughly a US 8–10. "Free size" is cut to a 55 or 66, about a US 2–6. Trendy boutiques and Dongdaemun rarely go above 66 and often have no returns. For bigger sizes: SPA brands (SPAO, 8seconds, TOP TEN, Musinsa Standard), the men's section, plus-size online malls (66girls), and global brands in Korea (Uniqlo, Zara, H&M) with full home ranges. Shoes are sized in mm; women's options thin out above 250mm (US 8) and are hard to find above 260mm. Online (Musinsa, Zigzag) lets you filter by size and read real garment measurements — more reliable than the label. Conversions vary by brand.
