I remember reading a story I quite liked a while back but I can't find it anywhere

The basic idea is that a group of people find that in an attic full of old boxes of clothes, but there were t-shirts with extra armholes, a pantyhose made for a humantaur, bras for >2 boobs, etc. When people wore the clothes, they'd transform.

Unsure if this is the correct forum to be posting a request , it may be an idea to have a separate requests forum.
