Etsy.com has alot of new vendors or people who will make your items to order and they are reasonable.
I had an all leather corset made for 55.00 plus shipping on esty.com
A lot of my guys order wigs from ebay, and there are also for sale or trade boards on
fetlife.com
Also on Ebay.com you would have to wait a while (month a few weeks/ from China) but I have ordered rubber doll and rubber outfits leather shoes etc from ebay for my sessions.
I just get their size ahead of time then place the order.
Just go on and search fetish wear. (you'll find tons of stuff in every price range from 0.01 to several hundred.) check it out..
Hope this helps!
