Almost all the shirts from Asia are fake, although they are very like real ones. Ask the seller, whether it is a real or fake, check the discribtion carefully. Don't trust any seller who's point lower than 10 or 20.
Some bastards, like a guy called Dobson, sell used shirts as new one. I suggest you check the shirts carefully when you receive it. Don't be cheated. Money is not easy to be earned.
