It's too big when I pull it over my shoulders like you are supposed to and the waistline drops far below my waist but it fits fine when I pull the sleeves closer to my neck for a boat neck look. I am about 115 lbs and 5'4 and a size small was a little too big for me. This was surprising because it fit so small on the models but I may just have it altered. Overall pretty cute romper and it was a pretty modest length as well. The ruffles at the legs and the floral pattern are my favorite part. Very cute for summer!
