Measure around the fullest part of the bust to determine your bust size. To determine your cup size, subtract your band size from your bust size. Low center front for plunging neckline. Plunge without push up. Keyhole detail at center front. Plain powernet wing for support and anchorage. Fixed fully adjustable straps to prevent strap slippage.
