After waiting for a long time, you finally receive your costumes.
So what you need to do first with them?
1. See the details. Check whether there is any broken on the costumes.
2. Try it on.
If the costume is large or small, contact them in time. The earliest time that you contact them, the quickest you could get the problem solved.
If the costume is large, and happily you are a tailor, you could try to fix it by yourself. If you are not in tailoring work, you need to take it to a tailor shop to fix it. That part's money, you need to ask the seller to pay.
If the costume is made a little tight, this would be a big problem.
