I am always searching for great tops to exercise in. It's tough to find ones that are cute, comfy, and functional for the right price.
I discovered that American Apparel makes this really sweet v-neck tank with shelf-bra. It's made of 95% combed cotton and 5% spandex. It's soft, yet fits snugly to move when you do.
I love that it comes in so many bright colors, not just black, red, and blue like so many other sport tops. And for the cheap price of only $19, you really can't go wrong.
This top is definitely for the type of exercise that doesn't require too much jumping or bouncing, if you know what I mean. It doesn't offer enough support for a run, but would be perfect for a brisk walk or a Pilates or Yoga class.
Fit's Tips: The only thing about American Apparel - their sizes run really small. I'd shoot for one size larger than you normally wear. Here's a picture of me wearing it in raspberry (size Medium).
