I suppose it depends on your body proportions. Like if you have small hips and butt. Or small breasts. I think out wouldn't fit past a c cup unless you have nice perky ones or implants. It's decorative and delicate not able to support or anything. As for the bottom half. They are super stretchy and s long as you don't have super size hips and butt they should fit nicely plus they are made for the cheeks to hang out.
Sorry i want finished with the listing. Some one came to the door so i got interrupted. Must of pushed the submit button by mistake. It is one size fits most.
