I got my leather harness at: http://www.sub-shop.com/index.aspx
hurry..the site is closing and the prices are phenominal...I'm really pleased with the quality as well.
However, since you're in the city I also highly reccomend Mr. S Leather on 8th st. south of market. it's my fav in the area. they have a much smaller womens section than they do mens but it's still my fave.
I'd love to meet this girly friend of yours.
