If you find yourself on the fashion side of TikTok, there are a number of viral clothing items that have definitely surfaced on your feed. Abercrombie’s drop-waist dress, Wolford’s celeb-approved Fatale dress, and too many Amazon buys to count are just a few of the internet-famous items on our radars. This summer, TikTok exploded with videos styling another mega-popular buy: the Outdoor Voices exercise dress. The fan-favorite dress was originally introduced in 2018, so while it’s hardly new, its influence has never been greater than it is now. Videos abound on TikTok of people reviewing the dress, styling it to go on their hot girl walks or gushing about the latest prints and colors.

As style people, we were curious to see what all the hype was about. A few of our editors got together to do what we do best and test-drive the exercise dresses for ourselves. We tried out four silhouettes that the dress comes in—the one-shoulder, the cross-back, the cutout Court dress, and, of course, the original exercise dress—and put them to the sweat test during our regularly scheduled Peloton rides and outdoor runs.
