Does anyone know who makes the dress that Carrie Underwood was wearing on SNL 2/23/08?

It was the post-writer's strike SNL episode with Tina Fey hosting. Carrie wore the dress during her first song, "All American Girl." It's a blue or green A-line with some kind of animal print on it. She wore it belted and it was BEAUTIFUL! I'm not a huge Carrie Underwood fan at all, but she looked amazing and I want that dress!
