There are some more problems than fakes....
Especially if you want to sell designer clothes you have to be very careful about the rights that somebody might have on that label.
In germany for example there is a guy who has a license for all the ed hardy clothes. and everyone who sells ed hardy (for example) on ebay without his permission is going to receive some uncomfortable letters from his lawyers.
And those who receive such letters have to pay the for the work of his lawyer which is not rarelyover 1500€.
I had a legal dispute with one of them. I won, but i'm never ever going to buy anything from ed hardy or ralph lauren or somethin else to resell it.
Actually there were nearly hundred shirts and polos left.... So i can choose one every single day to wear....

Nearly 90% of that stuff you get on wholesaleplatforms is fake.
I started to create my own "designerclothes". But Paris Hilton refuses to wear them.... yet.

I don't think that it's that hard to make a lot of money with designer apparel and accesoirs.
If you want to make fast money you just need a celeb to wear you shirt on tv or sth.
Just make it expensive enough.
Do you know Gena,George&Lucy Bags? No one knew that they were from a very small town in germany. They were the idea of a good friend of mine.
They were expensive, they were extraordinary and so women bought them instead of frees and company or other stuff.
If you want to start real business in clothing then you have to convince through quality like Ralph Lauren did.
He started in the mid sixties and now he has the largest brand for clothes worldwide. Think about that.
I recommend to anybody who wants to "wholesale" designerpolos and stuff to not do it. It brings more problems, than profit.
