You might want to check out http:///www.tribesmart.com - it's a social shopping/product discovery site.
We are looking for people to add interesting products (easily done via a browser button) and add reviews comments and blog posts.
We're not in fashion, we run a web agency - however we think this website could be a good platform for new designers, brands and writers to build their profile.
There is also a facebook widget, which feeds products to a facebook tab on your profile page if you choose to use it. It means you can add products and build awareness as well as invite friends to comment on your posts.
