"A lot of my workout tops are pretty thin, which means I tend to feel . . . on display during a class full of people, especially if the room is cold when we first get in. I love that this Nike Classic Wind Warp Sports Bra ($30, originally $40) is padded so I never feel self-conscious. It claims it's supportive for medium-impact classes such as cycling and dance, but I've worn it running and found that it's even supportive for a couple miles on the treadmill. Plus, I love the color!" — Christina Stiehl, assistant editor
