If you decide on a low-cut cocktail dress, you'll need to make sure that your bra is supportive and also that it doesn't peep out from the dress anywhere. Try on the bra you're planning on wearing with your cocktail dress well ahead of the party or event that you'll attend so that you can be sure you have a good fit, support, and that your bra straps or other parts of the bra don't show. Bras such as the Nordstrom Nu Bra (Buy Direct) are strapless, so you don't have to worry about underwear straps showing.
Concentrating on areas you want to smooth, select appropriate shapewear. Again, try on any shapewear that you plan on wearing with your cocktail party dress ahead of time to make sure it's working to show your figure to its best advantage.
