K Cup Bras and I Cup Bras — F to K Cup Sizes for Fuller Busts
Looking for a K cup bra or an I cup bra that actually holds you up? This collection carries F, G, H, I, J and K cup sizes together, so the hard-to-find cups sit in one place instead of scattered across a store that stops at DDD.
What a K cup bra size has to get right
At a K cup bra size there is no margin for a bra that is nearly right. Every bra here is engineered in Poland or France for heavier breast tissue. Narrow underwire that traces the base of the breast rather than compressing it. Side boning that keeps the bra upright through a full day. Three-part cups for natural lift and round shape. Wide adjustable straps and a firm band that carries the weight where it belongs.
- Full coverage, plunge, unpadded and lightly padded styles
- Extended band sizes and wide strap designs for steady all-day support
- Embroidered lace in beige, navy, red, green, pink and white
- Matching bra and panty sets available
Shop K cup bras, I cup bras and F cup bras
If you are looking for bras for K cup sizes, the Sevilla in white runs right through K cup and is the natural first try. The Cassandra in black covers J cup with a matching set, and Blanca is the quieter everyday option through G cup and H cup. Among our F cup bras, the Victoria pairs underwire with wide straps.
An I cup bra and a K cup bra are not the same fit, and neither converts cleanly from a US size. Two measurements will tell you which you need — use our bra size chart and calculator before you order. Band sizes 28–50, cup sizes B through M.
