Taylor Swift's Popularizing the Workout Dress — Here's Her Go-To, Plus 10 More

IUGA Workout Dress with Built-in Bras & Shorts ($36)

More than 3,200 people have reviewed this Amazon workout dress, giving it close to a five-star rating. It has thin, adjustable straps that cross in the back, and a full shorts-style bodysuit underneath. The built-in bra is equipped with removable pads, and is high-performance enough to sweat in, but also comfy enough for hanging out.

What reviewers say: Many Amazon customers love this workout dress for its ability to fit larger chests without being baggy in the waist, preventing thigh rub, and being just the right length. One new mom even calls it the "most flattering item I have ever worn."
