I read the reviews and got a xs bc i saw ppl saying it runs small. so i got an xs. for reference i am 5’2 and 127lbs. it fits and looks great! butttt it is definitely tighttt on my arms and shoulders and makes it difficult to raise my arms up. unfortunately it’s my birthday fit for this Friday so I can’t change my outfit. but definitely sooo cute! the material is definitely thick and not stretchy and kinda scratchy, but still cute!
