does anyone know what this bikini is called, or where i could buy one?

You could always Google "crotchless bikini".

that's the first thing i did, genius.

The closest I could find before I lost interest. I got alot of interesting hits off "Extreme bikini" in google and image search.

That looks like a custom set-up... It appears to have once been a normal bikini...

I still havn't seen any with the exact same top as in the original pic but I've seen bikini's with similar bottoms called "Bush Patch" and "Parisian" bikini bottoms or sets.
