You slip the black shirt on and wait to see if something happens. The first few moments, it seems like a normal shirt, but then it starts to sink into your skin, black fur quickly replacing your chest and arm skin, with a large patch of white fur on your chest growing over it, small pads quickly growing in the palms of your hands, tiny black nails coming out of your fingertips. These claws seem to be extremely sharp and hard, you can even scratch yourself with them quite painfully, nevermind other people...
You are now furred and clawed from feet to neck.
