True to size. 
Note from Sally: I own a few pairs of these shorts and I love them. They're extremely comfortable, prevent any "chub rub" and look cute on their own or layered under a fluttery dress. The colors look fantastic and have stayed true, not faded, in the two years I've owned them. 
This pair of high-waist shorts boasts a buttery soft feeling and impeccable style during training sessions and beyond. With a classic high-rise design, these leggings feature a flattering wide double-layered waistband with comfortable hidden elastic.
