A Portland, OR pair of dykes runs InHerTube, which sells "100% recycled rubber
custom made dildo harnesses and rubber accessories for women of all sizes."
They also advertise their products as vegetarian/vegan-friendly.
I just checked out their website - very friendly site, cute pictures of the
businesswomen, a variety of harness products (no thigh harness on the website
at the moment, but it's worth asking), according to their website they sound
quite fetish-friendly, and they take larger sizes into account.
The website is www.inhertube.com
