The original model for these is Costless. While he still has them listed on his website, I understand that he is no longer selling the finished pieces.

I have two - one which I bought from an E-bay seller which was made by Middle Eastern Manufacturing, and a coin one which is a vintage Costless. The vintage costume came mounted on a belt base and bra. I had to mount the MEM belt as it was diffucult to wear without it being mounted on something.
Now, the Costless is made with real coins from all over the world. The MEM is made from prestamped pieces of metal, including "coin" weight discs. I have had to take pliers to both sets.
Now, the nice thing about the MEM set is that I can play with it without feeling guilty. The top part of the belt and the accent pieces in front and on the side have black irradecent beads. I have added some clear crystals to the belt and am thinking about adding some coloured ones, but can't decide which colour!
As for additional sources, I believe that both Sarah Skinner and Jessinia have these costumes in stock, but that they both come from MEM.
