Home based business or multi level market that sells just bras?

I am searching for a multi level market opportunity that sells special sized bras and lingerie. Or would like some information on how to start a business. More like tips on how to get started and about how much you would think it would cost. I am not really interested in selling adult toys or other pleasure items. Just lingerie and bras. There aren't many places that sell bigger cup sizes for smaller women or any place around where I live that do. I have heard many people talking about how they would love if a store would open up where I live. So just any advice on how to get started or find a place that I could buy and sell or sell from a catalog would be helpful. Thanks in advance.
