Why do small cup busts need the best strapless bras? You might think they could just go without a bra.

But foundations are all about shaping and supporting us in our clothes. It doesn't matter whether you are big or small busted. You want to look your best in whatever you're wearing.

Strapless fashions can be tricky and difficult to fit, whatever your size. One style lays flat, has a sweetheart neckline, or has a deep, cleavage baring V-neck opening. The last thing a woman needs (as in "been there, done that") is to spend her time trying to keep her boobs in---or tugging at her bra to keep it up. It doesn't matter whether you wear one under your wedding gown, a sexy cocktail dress, or a casual summer frock. Why worry?
