Shop size 10D bras at Kayser. A 10D means a fuller cup on a narrow band, which calls for bras with good internal structure: firm, wide-set underwire that follows the natural curve of the bust, cups with enough volume to fully contain the breast tissue and a band that stays parallel to the floor without riding up at the back.

The Alive T-shirt Bra provides a smooth, well-structured everyday option in 10D. Underwire styles from the Be Real and Total Comfort collections offer lift and defined shaping for D cups on a 10 band. For wirefree support, the Total Comfort Wire Free Bra uses wide fabric wings that provide support without underwire, making it a comfortable option for 10D women who find standard wire channels uncomfortable.

With a D cup on a 10 band, the band is doing significant work. If your bra band rides up at the back or the underwire sits away from your sternum, this usually signals a band that is too loose rather than a cup issue. To resolve this, make sure you are wearing your bra on the tighest hook or try going down and band size and up a cup size. Learn more about sister sizes.
