i got an xs in this shirt and it’s not too tight or small on my arms which is amazing :) the shirt isn’t a sheer/see through material which is good! (for reference i at 5’1 with a size 32b cup size)
fit just right and super cute. I got the green because I was worried the white would be see through. the material is nice and thick you don’t even have to wear a bra. should have gotten both !
