thats a pretty sad stories i hear from this evil people/
the only time i ask to buy a costume was the misato from evagelion, who its a member at ebay name by honestchina. she does great work, and the costume came in excellent shape, size and the way i wanted. ^^ so there are good ones, just that be sure to ask lots of questions.
i did like, when exactly can i have the costume made? what type of material you use? any references like help from people, um skill? and so on. not wrong to ask questions but it also limits the choices of choosing a right person, and always when buying stuff from ebay check their feedback. if you happen to notice a negative feedback, it might be best if you avoid them.
