Begin by choosing a bra that offers enough support and is the right style for your dress - preferably from a brand name with which you are already comfortable.
Step 2
Slip on a strapless bra if your dress has a low or wide-cut neckline, or slender straps. The most versatile strapless is one with removable straps that you can make into a crisscross or halter bra. Buy underwire if you are full-busted or full-figured.
Step 3
Select a backless bra that hooks at the waist if your dress has a low-cut back. Let them see skin, not bra straps.
Step 4
Slim down with a Lycra or spandex slimmer. This modern-day corset will keep you looking trim; just make sure it's comfortable for an extended period of time, and take it along to your fittings - it can change the fit of your dress.
Step 5
Wear underwear that is comfortable, stays in place and doesn't show through the dress in any light. A pantyhose-underwear combination is a good choice for a slim-fitting skirt.
Step 6
Choose a sexy garter belt, if you dare - make sure that it shows no lines and won't snap during a dance.
Step 7
Purchase a slip if you are wearing a long sheath dress.
Step 8
Pick hosiery of any style, as long as its color flows harmoniously with your dress.
Step 9
Try on a variety of styles under your dress once you've chosen the proper type, and move, move, move. The bra should be comfortable and stay in place at all times.
