Black crochet knit tank top

Handmade unbranded crochet tank top in black. The crochet pattern is solid at the top chest area so that it can't be seen through but is looser with bigger holes that can be seen through on the bottom half--not sure how to explain but hopefully you can see in the pictures. I don't know the material but I would guess it is synthetic. Excellent condition, barely worn. There's no size but it fits XS with a bit of stretch. I'm usually an S in tops (34B) and this is a bit tight for me. Pet-free, smoke-free home, only washed with unscented soap. Let me know if you have any questions!
