I am normally the size 6 or an eight this does fit me with a little bit of room so I would say it can fit a medium up to a large and maybe even somebody that fits in an extra large but a smaller if that makes sense. It does have some stretch on the waist, the top is a breast cup, so it is a certain size I would say for larger breasts it would not fit maiden India the brand is band of gypsy it’s such a gorgeous material. I can’t even explain it again right under the breast where that kind of scrunchy material is it does have a nice stretch.
