Think I'll add some constructive input into this... Get some original designs down and get some feedback before you contemplate selling anything. No-one wants to see just a logo on a T or hoodie unless it's froma company that produces other things. Check out Man Made Clothing (google it) for some well designed and tasteful clothing styled toward an alternative consumer but still looking fresh as f**k. Do some research, get some designs down to get feedback, source some good quality blank clothing and get a few proto's out to see how it goes. Good luck with it, always nice to see fresh products from a different perspective
