This week's Fit Beauty Giveaway is sexy and functional -- we're giving one lucky reader her choice of one item from Dr. Rey's Shapewear Collection as well as an Enell sports bra.

What's great about the lingerie from Dr. Rey Shapewear is that, of course, it smooths and slims you under your clothes, but while other types of shapewear tend to look embarrassingly like granny panties, Dr. Rey Shapewear is sexy, even if your clothes are ... well, elsewhere.

Shapewear is great, of course, but you're a That's Fit reader, so we know your goal is not not need shapewear. So, we're also giving away a fabulous, super supportive sports bra by Enell. To enter, head over to the original post and leave a comment, but hurry -- this contest ends at 5pm Eastern Time today!
