Either this runs large or it’s true to size - hard to tell since I always have to size up with FN tops! I ordered the Large and it’s too big for me. I normally wear a Medium with other brands (I’m 145 lbs and 36C). The top is adorable and I love the big sleeves! It’s more like a bikini with arms so doesn’t cover much of your midsection. I might wear a black cropped tank under it. The fabric is light and breathes; maybe it will shrink if I throw it in the dryer but I wish I ordered my true size instead.
