At Brava, small band plus D+ cup is a specific focus.
The fit challenge for petite frames
A small band size with a larger cup creates specific fit challenges. The underwire needs to sit flat on the ribcage, not on breast tissue at the sides; if it sits on tissue, try a different size or a style with a different wire width. The cup needs to be set closer together than in a larger band size. And the straps need to be positioned for narrower shoulders — wide-set straps that suit a size 16 frame will slide off a size 8 frame immediately.
Ewa Michalak is one of the strongest recommendations for small bands at larger cups, with narrow, forward-projecting wires that suit a smaller chest wall. Panache and Freya also run small bands in their core styles, and Corin is a strong everyday option for petite frames.
What to look for
Features to look for on a petite frame at D+ cup: narrower underwires (check brand fit notes) and straps that sit centrally on the shoulder. Brands marketed as "fuller bust" don't always mean they suit petite frames — the two requirements (larger cup, smaller band) are separate, and not all fuller-bust brands address both.
