Runder Under long sleeve by Lululemon We like to mix things up, in our workouts and in our closet. That's why we designed this soft base layer to be reversible. We made it out of inherently wicking Running luon and gave it flat seams so it sits comfortably against our skin, no matter which way we wear it. - reversible for two looks in one [stock photos show one side, photos show the other] - contoured hemline with bum coverage - flat seams won't rub you the wrong way - thumbholes help keep your sleeves down while you run Size tag removed, but most comparable to size 8 measurements - however, review measurements prior to purchase to ensure fit. Approx. measurements: armpit to armpit: 17” length: 26” In excellent used condition with no visible signs of wear!
