Get a rear view
No matter how you pose in front of the dressing-room mirror, it’ll take extra effort to see your backside, says Stephanie Poli, a fashion blogger and TV editor. But it’s worth it. Get an accurate glimpse in a three-way mirror whenever possible. Or take out your makeup compact, turn around with your back to the dressing-room mirror and use your little mirror to check your reflection. If you have time, get an even better grasp on all-around fit by trying on two sizes of the same item.
