Spell Wildcat yoga set size small

Spell Wildcat athletic/yoga set size small. It's a little too tight on me and as much as I love the print, I need to size up. Only worn a couple of times. There is a tiny bit of wear in the bottom hem of the pants and the bust of the top, minimal but I like to disclose everything. In my opinion this is a true small, it's not oversized like Spell dresses and tops tend to be. It's stretchy but very supportive. The top has adjustable cross back straps. Pants are high waisted. Would swap leggings for the shorts in M.
