  • Push up bra: B-cup push up bras are staples for women with small breasts. They are designed to maximize cup sizes, making your boobs look natural. It also adds much-needed cleavage for a perkier silhouette on plunging tops.
  • Padded bra: A padded bra is another option if you have a B cup size because the soft padding can make the bust look more prominent. These are also well-designed to mimic the natural shape and movement of breast tissues.
  • Spacer bra: A spacer bra uses dual-layer foam fabric that makes it more lightweight than padded bras. B-cup spacer bras are great options if you want to avoid compression yet need a more pushup effect.
  • Triangle bra: The triangular cups provide enough support for small breast sizes like B cups. Since the straps are part of the top, there’s a greater pull on the cups to accentuate the chest better.
  • Adhesive bra: Studies suggest some restrictive materials prevent muscle tissue from growing, speeding up sagging. Strapless adhesive bras, including chicken cutlet bras and nipple covers, can stop your B-cup breasts from sagging. Even if these don’t have straps, they provide enough coverage to shape the bust.
