Peter had a habit of stealing clothes from his boys. A hoodie here and a jacket there. Sometimes it was a shirt depending on the day. Peter likes to wear his boyfriends’ clothes. End of story. Nothing could change that. So when a hoodie goes missing everyone looks at Peter cause obviously he took it. There is no question when Peter wants to borrow something clothes-wise, he can. They all just learned to live with it. Plus it was kinda hot for all three of them to see Peter in their clothes. Harley, Harry, and Johnny learned to accept that Peter would always steal clothes.
