Gym Shark Leggings Black and Grey Camo Scrunch Ruched Bottom Cute Size S/M?

Nice leggings in great used condition. No size tag but believe these are small or maybe medium. I would guess more of a small. They measure about 12 3/4” across waist and have about a 24” inseam. Cute scrunch bottom detail in the back. No harsh odors, smoke free home.
