Don't expect it to arrive on time or count on any customer service.
Ordered my costume more than a month in advance, when asking questions to try figure why nothing had changed for the order after a month the replies were completely unhelpful. My cosplay wasn't even custom sized so there shouldn't have been much in the way of tailoring. Now won't arrive on-time for when I actually needed it so basically a waste of time and money. Do yourself a massive favour and find a place to buy your cosplay somewhere that cares.
