This is so freaking cute, it's my new favourite set. I wanted a snug fit, so I went a size down, and it was still so comfortable, not too tight at all. It's pretty stretchy, so I feel like you can get your usual size. HOWEVER, the strings are really fragile. They're not really securely sewed on. One of the strings became loose after my first wear, but after restitching the seams, it was good for all the other times I wore it. If you've got a sewing machine, it's an easy fix. I feel like if you have a bigger bust, you might want to size up.
