Peter always steals his s/o’s clothes, always. Shirts, jackets, hats, pants, (you either drew the line or just gave up at underwear) because he loves wearing his s/o’s stuff so much It smells like them, it reminds him he’s so lucky to have such a wonderful s/o and he looks hot. And if anyone says anything he’ll speed back and model like 5 outfits all of his s/o’s stuff saying how he looks too good not to wear it.
