Really tough market. How much experience do you have within the fashion world? It sounds like what you are wanting is a majority stake investor. I don't think you'll find anyone willing to put up the cash and run the full business side of anything without owning a majority of the company. My suggestion would be, make some money first and get it moving forward. Then start looking for the partners/investors or you will get eaten out of your majority stake before someone puts their first dress on.
When I stand before God at the end of my life, I would hope that I would not have a single bit of talent left, and could say, "I used everything you gave me."
