Busty body types often have trouble finding an evening dress that fits well. You are either bulging out of the top of the gown or stuffed down in there looking flat and oddly lumpy.
The solution to this problem is a full-length, well-fitting strapless bra. Extending down to the bottom of your torso, a full-length strapless bra will hold you in place and smooth out your stomach area, making the dress fit better and look better proportioned.
Choose a neutral color and avoid a piece with a lot of extra embellishments. It should fit comfortably and just slightly snug. Too tight and you end up looking --- and feeling --- like a stuffed sausage the entire time you are wearing the dress. The idea isn't to look smaller or thinner --- but rather, to keep your breasts in place and your overall midsection looking smoother.
