Find the Right Underwear
Spinning around and checking yourself out in the mirror is no longer enough. Grab your roommate or S.O. and have him or her snap a photo of your look from the front and back — especially if the material you're wearing is thin. Running outside and letting the natural light shine down on you isn't a bad idea, either. It's not just contrast colors you should keep your eyes peeled for, but pantylines or the hem of a slip.
