Women's dresses & outerwear
Same 44-99 numeric scale as tops, but cut to fit the bust + hip together.
Korean women's dresses, one-pieces, and outerwear use the same 44 to 99 numeric scale as tops, but the size grading assumes both bust + hip fit the Korean median proportions at that label. A dress labelled 66 presumes a body that fits a 66 top AND a 27-28 jean. Pear-shaped or apple-shaped Western buyers often size out of this assumption: a 66 dress may fit at the bust but be tight at the hip, or vice versa.
For most short trips, this is the category where Western buyers get the most wrong. The two-fit assumption means trying the dress on is more important than for tops alone. Fitting rooms at Musinsa flagship Hongdae, Olive Young Myeongdong's small fashion floor, and the major department-store K-fashion floors (Shinsegae Main, Hyundai Yeouido) accommodate fitting easily; smaller Instagram-brand shops (most of Garosu-gil) often have 1-2 fitting rooms with a queue.
Outerwear (coats, jackets, blazers) follows the same scale but cut for a layered-underneath fit, so the nominal size runs roughly one size larger than the matching top. A 66 coat fits the bust looser than a 66 tee, intentionally - the coat goes over a sweater + tee. Korean-domestic outerwear from MIXXMIX, NAIN, and similar tends to run slimmer through the body than American outerwear; expect to size up if you are between sizes.

How to read your size
- Take both bust and hip measurements in cm.
- Find the row where BOTH fit.
- If bust and hip fall in different rows, size up to the larger.
- For outerwear, the same nominal number runs looser; check the brand chart.
Fit notes
- Dresses assume Korean median bust + hip proportions at the same number.
- Pear / apple Western frames often size up for hip or bust separately.
- Outerwear at the same number fits ~1 size looser than tops (layering allowance).
- Length hits the Korean median knee position; tall frames get above-knee on midi cuts.
Brand quirks
- MIXXMIX Slim cut. Size up.
- NAIN Korean-domestic preppy. True to size at bust, slim at waist.
- STYLENANDA Slim, Korean median proportions.
