Like others have said, order a size up, if possible.

I was feeling risky and dangerous and ordered the size I normally wear in skirts. It fits - but just barely. It's one of those skirts that I have to hold my breath to put on and I can't eat anything while I'm wearing it, but otherwise it's incredibly cute with no issues.

I decided to keep it to see if I can use it as a goal to work for when I go to the gym. We'll see if I can drop enough weight to get it to fit without being too snug.
