Alo Yoga has some serious street cred. With celeb fans like Hailey Baldwin, Kendall Jenner and Gigi Hadid, it's not a hard sell. If you're just jumping on the bandwagon, get yourself a pair of the brand's moto leggings, which are just as good in the gym as they are out. Don't you feel cooler already?

Carbon38 is an online retailer, specifically aimed at the fitness-loving set.

Perhaps the most daring of workout clothes we've come across, Michi is not for the under-the-radar girl. The bondage-like designs are intricate and sexy, but still fierce and tough.

Spiritual Gangster is you're inner hippie come to life.
