Our future fit activewear is compressive and flattering, but also very stretchy, high waisted and forgiving, so although this table is a great guide, if you’re on the fence with sizing, think about how you love your activewear to fit and if you want to be hugged tight for your HIIT workouts, simply size down, whereas if you like things a little comfier for all-day wear, it’s probably okay to size up too.
