Yes, the fabric came like that. It's a blue snow leopard print on a spandex fabric. It didn't cost me that much since I had a coupon, about 6 bucks. But then again, for such a tiny Preddy, I didn't need a lot.
Depending on the weight of the fabric, it can cost you between 6-15 dollars a yard. And for a standard catsuit (high neck, long leg and sleeve), it would take around 3-4 yards. Depending on the width of the fabric.
Kayla's suit was a really simple pattern. Single piece front and two piece back with tube shaped arms and a zipper down the back. When you work with a really stretchy fabric, you don't really need a perfect pattern.
As far as patterns go, you can use one of three methods. A) find someone that makes bodysuits. not that cheap but worth the headache of making your own B) Make your own pattern using the ducktape dumby technic. or C) Find a catsuit pattern online or at the fabric store. The third option may be more difficult for a male form however. Here's a site you can go to to get a good idea on making a bodysuit.

For her gloves, I just traced her hand in an opened postion, added a extra 1/4" in the width for the seam allowance, and then cut a front and back. I sewed them together using a zigzag stitch.
For the feet I just stretched the fabric over the carved foam base and hot glued it in place.
But if you want a simple and comfortable bodysuit, then I recommend going through these guys. Their Pred suit is awesome, and as good as you're going to get other than doing the whole latex Mr.I muscle suit ordeal.
