Love this jumper! True to size! Your boobs will pop but not to the point where u need to adjust. I’m a 36 H. Everyone said to size up but I went with a medium anyway and I’m happy I did. It hold everything in place. Go with the size you normally wear. I know I can fit in a medium depending on the material so I went with medium. The material has stretch to it. It is not denim material just so people are aware.
