How Korean Clothing Sizing Works (KS)
Korean Standard (KS) for clothing uses numeric sizes. Women: 44, 55, 66, 77, 88, 99 (mapped to bust ranges). Men: 85, 90, 95, 100, 105, 110 (chest cm). K-fashion brands often relabel.
The Chart
| KS Women | Bust (cm) | KS Men | Chest (cm) |
|---|---|---|---|
| 44 | 79 | 85 | 85cm |
| 55 | 82 | 90 | 90cm |
| 66 | 85 | 95 | 95cm |
| 77 | 88 | 100 | 100cm |

Notes
K-fashion brands targeting young consumers (Stylenanda, Chuu, Mixxmix) often use Free Size or one-size labeled. These run notably small — typically fitting US 0-4 only. International expansion brands (Uniqlo Korea, ABC-Mart) keep KS sizing.
