360 Back Smoothing Lightly Lined T-shirt Bra

Just purchased in December and only wore like 4 times because who wears a bra when you’re WFH and have lost any desire to have fun outside of the home! AMIRITE LADIES!!! Despite it not having a lot of wear, there is a pink stain on both armpits. I’ll have my mom try to get it out— she’s a magician.
