Designed to Fit. Made to Feel Good. Explore Our Bra Cup B Collection

When you’re a B-cup, you’re right in that sweet spot—but let’s face it, not all bras get it right. At The Foundation, we believe that every cup size deserves thoughtful support and everyday luxury. That’s why our Bra Cup B collection is packed with perfectly-fitting styles that don’t compromise on comfort, shape or beauty.

From everyday essentials to chic, fashion-forward pieces, each bra is handpicked from trusted international brands like Chantelle, Simone Perele, PrimaDonna and more. Think contouring fits, wireless ease, and soft fabrics that move with you—no pinching, no padding drama, just bras you’ll actually want to wear.
