Lululemon Power Pivot ribbed reversible tank in Scream Green Light. It's in great condition other than some makeup stains along the inside. There's one mark on the front (pic 4) but all others are on the inside so not visible while wearing. I feel pretty confident they would come out with a wash but I just haven't tried. No size dot on this style but fits like a 4 or a snug 6 (I wear a 6 in lululemon tops and this feels fairly compressive, so would fit either a 4 or a 6 depending on the fit you want).
