I’m thinking that when Sherlock first finds out about John’s transformation, he goes home and gets a bag of his own clothes to give to John, who’s lost his. He finds John sniffling in embarrassment with tears on his face, but Sherlock acts like it’s no big deal and asks John all sorts of excited questions, and John thinks this could be the best friend he’ll ever have.
