Welcome to the site Rick. After you do some reading on these forums, you'll probably come to the same conclusion as others - that 99% of the items on DHGate are not authentic. You do take the risk of having your shipment seized by Customs if they are presented as authentic. I think DHGate is a good source for some items but not for anything that is sold under a brand name unless the seller is able to offer some sort of release documentation from the brand owner.
Also do some reading on the DHGate escrow service. In spirit, it would allow you to recover your funds if you had a shipment lost at sea or even confiscated by Customs, but in practice I don't know what would happen.
Know of any good sources for name brand men's clothing (Bape, Red Monkey, etc.)
I've also seen the exact same men's clothing from DHgate selling on ebay as authentic. I wonder if ebayers know the difference.
