How the item groups differ
| Group | Available sizes in this listing | Price range | Total listed inventory |
|---|---|---|---|
| Briefs | M, L, LL | ¥364–¥528 | 142 |
| Bras | A80, A85, A90, A95 | ¥1,320–¥1,585 | 67 |
| Short-sleeve running tops | L, LL | ¥726 | 44 |
| Sleeveless running tops | L, LL | ¥660 | 46 |
The labels distinguish briefs by M/L/LL sizing, bras by A80/A85/A90/A95 sizing, and both top styles by L/LL sizing. Compare the listed size convention within its own group rather than treating brief, bra, and top sizes as interchangeable.
What can be confirmed about the Kaiteki Koubou line?
GUNZE identifies Kaiteki Koubou as an underwear line and its official store presents women’s categories that include briefs, bras, and inner tops. The current YUBI100 listing also includes all of those groups. Because the exact manufacturer item codes and composition details are not shown for each Shopify option, this article does not assign a fabric, construction, or functional claim to individual selections.
For the currently available choices, see the GUNZE Kaiteki Koubou product page. Prices and inventory can change after publication, so check the product page before ordering.
