These are publicly available fursets. The fursets are designed to change colours constantly while they are being worn. They have more options than is shown (for example, there is also dragon wings, ears, and tail for the one on the left)

I made this video to show how it changes because a picture just does not do it justice.

The one on the left is made by myself, Mewcifer, and is called Power Rave. My IMVU Profile where you can find information about me and custom products I make. My IMVU Catalog where you can buy public fursets.

The one on the right is by my friend, Nikawh, and is called Sassafras. Her IMVU Profile Her IMVU Catalog where you can buy public fursets.
