What does convertible straps on a bra mean?

Convertible straps on a bra means that the bra straps can be unhooked to create different strap configurations. Convertible straps gives you the power to adjust the straps so they work with as many clothing styles as possible.

Some convertible straps only unhook at the back of the bra, which allows bra straps to be crossed in the back and worn under racerback tops. Crossing straps in the back can also make your bra more supportive.

Other convertible straps fully unhook at the front and back, which means the bra can be worn strapless, with one strap, or with both straps crossed in the back.
