Build a Clothing Brand

I need 100 Designs to build a clothing brand. We would start with T-shirts, then we will go after other items in order to build a strong brand. I would need good ideas and excellent designs that make a difference in a very bussy clothing market. The brand name is Geek&Fun and the website is geekandfun.com / the spirit of the brand is something cool and fun, it can relate to geek stuff as well. In the beginning the idea was to make up a website where people could find any kind of passion related clothing (NICHE). It can still be that way, but i want to push it forward to unique designs that represent the brand.
