Lululemon Vintage orange tank size 8 EUC

This is a GUC vintage tech Lululemon tank (unsure of style name). The colors are orangish, silver, and a pinkish beige color. I believe this is a size 8, the armpit to armpit measurements are approximately 15. Please check your measurements before you buy to make sure it will fit. Only flaw I noticed on this app as the bottom back has a small mark on it. The mark may be from dust or it may be a stain, unsure. I did not try to wash it to see if it will go away.
