I have had a look at their site and they have many brands listed but they are not authentic and genuine. I would not recommend purchasing from them as you would end up breaking copyright/trademark laws if you sold them as branded items. They also do not provide relatively secure payment options like Paypal or credit card so you have no guarantee that you will receive goods after you have paid.
If you are looking for authentic branded clothing check out Link hidden: Login to view

. Both state on their sites that their products are genuine.
All the best :)
