Hi, I'm planning to order this costume in the very near future and just wanted to check on a couple things...is the actual costume a one piece costume? I ask because you describe it as a dress, though I don't see any zipper in the back of the outfit and am wondering how it would slip on. Second, for the gloves, would you need any arm measurements done for them? Just want to make sure I have all that info ready if needed when I do order this costume. I'm looking forward to eventually ordering this costume (not planning to use it until a convention next July so not in a rush at the moment), this will be the 6th costume I order from you and I will continue to do business with you in future for all costume needs as your prices are great and the quality is phenomenal :)
