anyone here has any experience doing clothing business?

im planning to sell sports clothing from world renowned brands at more than half the price of the actual product (latest stuff too)..not like the sportsdirect crap which is out of season or those warehouse sale

eg: Tshirt RM120 at the boutique, we buy at rm30, we sell at RM50 (40% profit).

Profit margin can go as high as 70% for some items.

Suppliers I have (funny what u can find at dodgy areas of the Klang Valley)..just need a partner for marketing and capital maybe

target market is everyone, but trying to aim for Chinese as im 99% sure they have no idea how to get these items

I have a feeling this is gonna be a big hit as judging from the response of my sports loving family member and some close friends they were buying these clothings without even thinking of the price because its so worth it..lol

so anyone keen to join me and try to come up with something?
