Lululemon racerback tank

LULULEMON Cool Racerback II Tank Color: Wee Are From Space Ice Grey Alpine White (Basically a light grey with tiny grey stripes) Snug fit with really good quality/thick material. Too big on me after weight loss. Unfortunately, the tag is missing but it is confidently a size 10 or 12 and after trying on my friends it can fit both! Pre-owned so it has some minor pilling in areas- I tried to photograph/video but it is hard to tell.
