The Catwoman whip from Batman Returns is "The Australian Whip" from Terry Jacka, an Australian whipmaker who's stuff you can find from David Morgan or Western Stage Props. Terry's been making whips for over 20 years now, and his stuff is, in my opinion, some of the best out there.

David's prices are about the same on Jacka whip when you factor in shipping, but you can't specify color from David.
Word of warning if you're looking for a "Screen Accurate" whip though:
Terry doesn't make them like he used to though.
The transition between the handle and the thong, (the braid,) is a lot stiffer, and the handle is a little thinner, (he used to use cane for the handle foundation, now he uses fiberglass.) I've played with both n my humble opinion as a whip artist, the design changes produce a much better whip. I've got one in 6' that I use for targeting and multiple cracking routines in shows, and it is a dream.
Sorry so long in reply, but I JUST joined. Been lurking for a while.
If anyone has any further questions about this whip, or any other whips in general, drop me a PM, and I'll help out where I can.
