It's possible that the simplest piece of clothing you own is also the one that makes you the best looking.

A new study out of England found when men wear a plain white t-shirt, women rate them instantly 12% more attractive than when they're wearing anything else.

And the more out-of-shape you are, the better the results. If you're in good shape already, the white t-shirt will only help a little . . . but if you're not, the white t-shirt is going to work magic.

The plain white t-shirt made men look like they had broader shoulders and smaller waists.

The study also found the least attractive thing you can wear is something that draws attention to your stomach - even if you're in good shape.

When men wore a t-shirt with a capital letter "T" on it, women found them attractive. But when that "T" was flipped upside-down, so the long part was across the stomach and not the chest. Women found the guys much less attractive.
