Shopping for bras in South Korea

Korean sizing mirrors the Japanese system: centimeter bands (65 to 85 dominate shelves) and cups printed before the band. Like Japan, cup letters run fuller than EU by roughly one letter, and ranges above a D-equivalent thin out fast in domestic brands.

K-brands emphasize seam-free molded styles and youthful bralettes; full-bust support above KR D is largely served by imports.

Brands you will commonly see: Vivien, Venus, Yes, imported ranges.

How South Korea writes a bra size

South Korea labels bands in centimetres rounded to fives, following the Japanese convention rather than a local one.

As in Japan, the letters run roughly one place fuller than European for the same body, so converting from a Western tag usually means dropping a letter.

The cup is printed before the band, as in C75.

KR size conversion chart

Every row is one body. The KR column is what the label prints; the others are what the same bra is called elsewhere, which is what you need when a brand ships from abroad.

Frequently asked questions

What bra sizing system does South Korea use?

South Korea primarily uses KR sizing conventions in mainstream retail, though imported brands can carry other systems' labels. The calculator above highlights your KR size and shows all 7 systems for imports.

Which bra brands are common in South Korea?

Commonly available names include Vivien, Venus, Yes, imported ranges. Local availability shifts, and each brand's own centimeter chart beats any converted label when they disagree.

What is a US 34DD in South Korea sizing?

A US 34DD is a F75 in South Korea. The same bra is a UK 34DD and an EU 75E, because the cup ladders diverge after D.

Do I add inches to my underbust measurement in South Korea?

No. The old habit of adding four or five inches was written for non-stretch fabric and produces a band about two sizes too loose on a modern elastic one. Measure snug and level, and use that number directly, whichever system the label uses.
