Has anyone ever purchased anything from Juicy Couture in numerical sizing, versus the lettering? I was wondering what the sizing was like - whether a "2" is really a size 2? I don't really trust their sizing guide, and haven't been able to find something in the numerical sizing locally to try on. I'm interested in ordering a top online, but it's done numerically, and I would hate to order the wrong size. Any advice would be appreciated! Thanks!
