What are balconette bras? The cups on a balconette bra offer a little less coverage than a classic demi bra for an added emphasis on your natural cleavage – not on a push-up bra level, but it gives you some room to show off the top part of your breasts. The bra straps of a balconette bra are set wider apart for an added emphasis on your natural cleavage and they’ll sit closer to the edge of your shoulder – but never fear, the bra straps of a great balconette bra should never slip of your shoulder.
