1. Splendour New Diamante Backless Bra , $55. 2. Maidenform Breakthrough Backless Underwire Bra, $28. 3. Ultimo D-G Collection Low Back Strapless Bra , $70. 4. Victoria’s Secret 100 Way Bra , $50. A bra is definitely necessary, yet a bra strap showing a la Carrie is just not cute (in my opinion). Thankfully there are quite a few ‘backless’ bras on the market : corsets with low backs, bras with whisper thin back straps, and other contraptions to give you the backless look along with lots of support: The Splendour New Diamante Backless Bra has two string of crystals as the back strap. Love!
