Korean fashion looks easy on the rack — until the size tag says 55 or 95, the fit is slimmer than your usual US/EU size, and the return desk asks for tags, receipt, and a short window.
Takeaway: measure in centimeters, try on in person when you can, shop neighborhoods by vibe (not by hype alone), and assume returns are stricter for tourists than for residents.

At a Glance
- Korean clothing often runs smaller / slimmer than typical US or EU cuts — use cm measurements, not only S/M/L.
- Women’s tags may show 44 / 55 / 66 / 77; men’s often 90 / 95 / 100 / 105 (rough chest cm for many men’s tops) — charts vary by brand.
- Best first stops by vibe: Myeongdong (명동) tourist-friendly; Hongdae (홍대) youth street; Seongsu (성수) concept / trend; Gangnam / Apgujeong (강남·압구정) polished & luxury; department stores for one-roof browsing.
- Passport for tax refund at participating stores — see our tax-refund guide.
- Returns: keep tags + receipt; tourist windows can be short; many online platforms need a Korean address/card — verify each store before you buy.
1. Why Korean sizes feel different
Most traveler guides agree on one general rule: Korean fashion often runs 1–2 sizes smaller (or simply slimmer) than what you wear at home. That does not mean every brand is the same.
| System | What it often means | Rough international match |
|---|---|---|
| Women’s 44 / 55 / 66 / 77 / 88 | Legacy Korean “body type” labels | Often maps roughly toward US XS→L — brand charts disagree |
| Men’s 85 / 90 / 95 / 100 / 105 | Often tied to chest circumference (cm) for many tops | Roughly XS→XL — still brand-dependent |
| Free size | One size, often cut for a smaller Korean average | May fit approx. women’s US 0–6 / Korean 55–small 66 — not “one size fits all” |
| SPA / global (Uniqlo, Zara, H&M…) | Usually familiar letter sizes | Still try on — Asian fit lines can run slim |
In the fitting room: (1) Check the size chart in cm. (2) Compare to a top or pants that already fits you at home. (3) Prefer trying on jackets, jeans, and free-size dresses. (4) On Musinsa (무신사) and similar apps, read SIZE & FIT plus height/weight reviews.
Note: online conversion tables are starting points, not guarantees. Prefer the brand’s own chart.
2. Where foreigners actually shop in Seoul
Myeongdong (명동) — easiest for first-timers
VisitSeoul describes Myeongdong as a major tourist shopping hub with street retail, casual fashion, and cosmetics clusters. Good for SPA flagships, accessories, gifts, and tax-refund–aware tourist density. Expect crowds; store hours vary.
Hongdae (홍대) — youth street & indie vibe
Around Hongik University: streetwear, indie boutiques, vintage, sneakers, evening energy. Good for trend pieces and budget-to-mid casual looks.

Seongsu (성수) — concept stores & current K-fashion
Former industrial area turned cafe + pop-up + brand destination. Press coverage highlights emerging designers, concept retail, and large fashion platforms’ offline spaces (including Musinsa’s Seongsu presence). Good for trend-led Korean brands — weekends can mean queues.
Gangnam / Apgujeong (강남 · 압구정) — polished & luxury
Higher-end streets and malls. Good for department-store fashion floors and designer browsing.
Department stores — Shinsegae (신세계), Lotte (롯데), Hyundai (현대)
One roof for Korean and international brands, clear fitting rooms, and staff used to tax-refund questions.
SPA & global fast fashion
Global SPA brands common in tourist areas include Uniqlo, Zara, H&M. Korea’s own SPA-style brands (often cited: SPAO (스파오)) are useful for trendy basics — confirm the branch and current collection in store; do not assume stock from blogs.

3. Shopping modes: streets vs apps vs brand stores
| Mode | Good for | Foreigner tip |
|---|---|---|
| Street / boutique (Hongdae, Seongsu) | Unique looks, try-on | Ask return rules before paying |
| Department store | Fit variety, tax-refund familiarity | Keep all receipts together |
| SPA flagships | Basics, quick wardrobe refresh | Check Asian vs regular fit if labeled |
| Musinsa (무신사) | Huge Korean fashion catalog + offline megastores | Use cm charts; online returns can be strict |
| Stylenanda (스타일난다) | K-fashion / beauty lifestyle brand known to travelers | Use official channels for store & return info |
| ABLY (에이블리) | App-first women’s fashion marketplace popular locally | Overseas delivery / returns may differ — verify before checkout |
These are shopping styles, not endorsements — confirm stock, prices, and policies yourself.

4. Tax refund (short pointer)
Clothing and accessories at participating Tax Refund / Tax Free stores may qualify if you meet tourist rules (commonly cited: about ₩15,000+ per receipt, passport, unused goods, leave within the stated period).

Quick habit: look for Tax Refund / Global Blue / Global Tax Free stickers and ask at checkout: “Tax refund, please.”
5. Returns & exchanges — the careful truth
- Tags on + receipt are usually required.
- Worn, washed, or damaged items are commonly refused.
- Tourist return windows can be short — ask the store; do not assume a US-style 30-day policy.
- Sale / final-sale racks may be non-returnable.
- Online: many Korean apps expect a Korean shipping address and local payment for returns. Musinsa Global Help Center states returns for simple change-of-mind or customer size mistakes are generally not accepted — measure carefully; defect claims need evidence.
- Department stores often have clearer English help — still confirm the day count on your receipt.
Visitor strategy: try on thoroughly in store; buy once; leave return as a backup, not a plan.
6. Packing & try-on checklist
- Know chest / waist / hip / inseam in cm.
- Bring one well-fitting T-shirt for comparison.
- Prefer late morning / weekday for quieter fitting rooms.
- Photograph hangtags + receipt.
- Leave suitcase space for layers.
FAQ
Q. I wear a US Medium. What Korean size am I?
A. No single answer. Rough charts often put women’s US M near Korean 66, and men’s US M near 95–100, but slim cuts and free-size pieces break that rule. Use cm charts and try on.
Q. Is Free Size really free?
A. Usually no. It often fits a narrower Korean average range. Check length and chest width in cm.
Q. Can I return Musinsa online orders if the size is wrong?
A. Musinsa Global Help: returns for simple remorse or incorrect size selection by the customer are generally not possible. Follow SIZE & FIT and their Help Center for defects.
Q. Where should I go for one afternoon only?
A. First Seoul fashion day: Myeongdong for easy browsing + tax-refund density, or Hongdae for street style. Add Seongsu if you want concept stores and have extra time.
