The gorgeous look you're after when you wear a designer prom dress can be compromised by wearing a bra that is incorrect for it. So, pay a little consideration as to what bra works best for your prom gown. If you're not sure what bra would work best for your prom gown, take a look at the list or gown styles below and what bra accompanies it.

Strapless Prom Dresses

These are very popular for Prom and require a strapless bra. Ideally, the bra should have boning or underwire support in the band and/or sides of the cup. Because the bra doesn't have straps the underwire/boning is to give your breasts the extra support they need. You may also need a bra that comes with adhesive strips that will help keep the cups in place. Comfort is an issue with underwire bras; many women quickly feel uncomfortable wearing this type, so before you buy that designer prom dress without straps, make sure you'll be okay wearing an underwire bra.

Halter Neck Prom Dress

Again, this is a very traditional style, but it does require a halter bra to accompany it. Buy one with adjustable straps and be sure that the straps are thin enough to be discretely hidden under the straps of the dress.

Plunging Neckline Prom Dress

This style is becoming more and more popular as they can enhance a woman's bust and make her look very sexy. You need a demi-cup bra with underwire. If you're on the small side, you might also consider a bra that comes with extra padding that will enhance your cleavage. It's essential that when you buy the bra, you take along your gown; you don't want the embarrassment of bra cups being visible when you wear the dress to Prom.

Column Prom Dresses

This style is rising in popularity as more teenage girls want to look like their favorite movie stars. The Jovani prom dress collection is very popular for this style. Column designer prom dresses hug every contour of the body and can look very sexy. For that perfect look, choose a full-torso bra that extends all the way from your breasts to your hips. Ideally, it should have a thick, tight microfiber so that it will smooth out your curves and make you look even more slender and sexy.

Backless Prom Dress

Gowns like those from the Flirt prom dress collection are helping to make this style more popular. For this style of gown you require a bandless, strapless bra. Obviously, as the bra has no band or straps, it requires adhesive strips on the inside of the cups to keep them in place. This type of bra doesn't offer much support but a backless prom gown does look sensational.

One final piece of advice; don't wait until Prom Night to try the bra and dress on together. Try them both on together well beforehand. This way you can make any changes that are required and even buy another bra if necessary. Testing out your bra and designer prom dress will also give you the confidence that you're going to look your best for Prom.
