One of the items on offer is Anthro Clothes. On the surface, they look like normal clothes, with the exception being that pants, shorts, underwear, and the like include holes or slits in the back to accommodate tails. However, the clothing is enchanted. If one or more articles of clothes come into contact with an animal, they will fling themselves onto the animal and shrink or grow to the animal's size. Once they are properly worn, the animal will become anthropomorphic with human intelligence, bipedal movement, opposable thumbs, and the ability to speak. The anthro will however remain the identical size they were as a normal animal. It also won't alter their personalities, so it is recommended to use them on more friendly animals or who are at least in a pleasant mood at the moment. If a human tries to wear them, nothing will happen.
Be warned. The transformation is permanent. Even taking off the clothes will not reverse the transformation. Therefore, use them carefully.
