Lululemon Cool Racerback Tank Top in Incognito Camo Jacquard Alpine SZ M? EUC

Lululemon Cool Racerback Tank Top in Incognito Camo Jacquard Alpine White Starlight. I don’t see a size dot anywhere but I’m guessing this tank would be best for someone who usually wears a medium - since I’m not sure please see measurements below. I do not know what material this is made of but it feels like a nice weight stretchy knit. In excellent used condition and from a smoke-free home. Armpit to armpit 15” Length 27” EDBCC
