Lululemon Run: Split Singlet Angel Wing Large

This is a GUC-EUC Lululemon Run: Split Singlet - Angel Wing tank. I believe this is a Sz 10 (or 12 but probably 10) because the armpit to armpit measurements are approximately 19.5, this tank is supposed to be looser. Only flaw I noticed is on the back left shoulder there is a small gray spot. I thought it might be dust spot but my roller didn’t remove it. I have not tried to wash it after inspection so it may come off with wash. Has been in storage for years, so may have missed additional flaw.
