Size 4 or 6 LuluLemon Wunder Under High Rise Black to Grey Ombre I'm 95% sure these are a 6, but they feel a little more snug than my 6's but still fit!!! I wear a 6 majority of the time but already took out the inner tag unfortunately!! Pretty much like new but has one very small repaired hole on the right butt that was repaired *at Lulu lemon seamstress* so barely visible when wearing them! The coin is for size reference!
