Extras: Your bra : Your dress

A bra can make or break your overall look. Get fitted by a professional, then go shopping! Oh yeah, make sure to bring your dress!

Pro tip: Don't assume a bra will fit! Labels can be misleading - and who cares if it says 34B or 34DD? Always try a bra on. It's the fit, comfort and support that count, not the size printed on the label.

Go ahead, take the plunge!

Pro tip: Make sure your bra is snug enough to stay in place, no matter how crazy you get on the dance floor. Hint: it shouldn't ride up when you raise your arms.
