@thunderfirewolf: With sites like those (Chinese sellers), anything they state to be "custom made" isn't actually custom made to fit you. The costume would have been pre-made, and they would of matched the sizes you provided with one of the costumes they made. That's why it would not have fit you in every area, for some other people, they can get lucky.
Another reason why it wasn't custom made is because it only took "6 weeks", they stretch out the time to make it look as if they're making it, because a costume doesn't take that long to ship. Probably in a week or three maximum.
