Gap Sheer white Button Down Shirt, XS

Gap brand new with tags. Sheer button down shirt. 55% Ramie 45% Cotton I’m shown in the top to let you see the style. Is it fitted? Is it oversized? I really can’t tell because it doesn’t fit me. I’m a size 4/6 pants, usually a small top with 32G girls. I didn’t try to button it but it’s possible I could have. I’m dying I wish this was still my size. I use to be so much smaller before I had children!
