Thanks for the input xandi.  I was looking for a shelf bra for a render a while ago.  Amazingly enough, in the 154 gigs worth of crap I've accumulated there was not one shelf bra.  Tons of semi's, demi's, plunges and full cups but not one shelf.  I, personally, think they're extra hot so I decided to make one myself.

Like I said in the original post, materials are still a work in progress.  Wanted to get the shape right and then go from there.
