GUC Lululemon sleeveless top, size 4, white with silver stripe

Originally for running, worn for several seasons casually but no obvious stains, pulls, or pilling. Sleeveless style that cuts down a bit under the arm. Very breezy, looks great over a colored sports bra or worn alone. Lower back is a smooth athletic material, body is a soft cotton blend. Tags removed by me, confirmed a size 4.
