Yup, that's her, and I'm a big fan :) I actually attempted her for a Charlotte area con this past January... Used a blue tank top I had, bought the skirt, hat, and some leg warmers from eBay, and got a cheap brown Halloween wig from a drugstore. Didn't look the best, but I had a fun time and a few people wanted my picture :) Since, I've got a much better looking wig, but sadly, no cosplay outfit of her (and I kinda want a decent looking one this time around :P ) I do have the name of the one I commissioned for my (good, partially complete) Leaf cosplay if you want. He's based in NC but I do believe he can ship them out.
Haven't seen Romeo x Juliet, but if college ever gives me a break, I'll check it out :3 Good luck on the job hunt and the cosplay!
Oh, and I bought the school uniform from "To Heart" as my cosplay for AWA. It'll also give me a chance to give my wig a test run :)
