I’m typically in between sizes depending on stretch and this shirt has non whatsoever. the material is amazing like it look and feels super expensive but not one stretchy at all. I got an xl thinking I’ll have extra room and I was mistaken… the arms part I can barely move and it barely covered my breasts and I’m only a c cup. I should’ve sized up 2 sizes. it fits but you can’t move in it. . the arms are also long which isn’t bad but the shirt itself is so cute. I’ll hold onto it but I wish I went up 2 sizes
