The 11 Hottest Arm-Bra GIFs Ever

First of all, you may be wondering, what exactly is an arm bra and how is it different from a hand bra?

The difference is quite literal. A hand bra, simply, is when a girl holds one boob in each hand. An arm bra, however, requires her to cover and/or hold up one or both boobs with just her arm (or arms) -- without using her hand. To illustrate the distinction, we've curated the 25 hottest hand-bra GIFs over here, so you can compare them with the arm-bra GIFs below, featuring Emily Ratajkowski, Emmy Rossum, Nina Agdal, Kate Upton, Scarlett Johansson, Genevieve Morton and more.
