It’s a size small but I think it definitely fits more like an XS. It was too small for me! I’m 5’3 and 115 lbs, 34b and have a longer torso. It’s so cute and I wish it fit but it’s just too tight. Hope it works well for you. Reposhing this item I purchased from @ej_sansav. Loved it, but ready to rotate for something new. Questions? Leave a comment below!
