Perhaps in a post - apocalyptic fanfiction setting, resources are scarce and Peter finds Tony's clothes. Wearing them gives him a sense of hope and protection. It could be that the clothes have some built - in defenses that Peter discovers while wearing them. Or maybe Peter is trying to inspire a new generation of heroes by wearing Tony's iconic clothes. He could tell stories about Tony to the younger ones while wearing them, passing on Tony's legacy in a very tangible way.
It could be for a bet or a dare. Peter's friends dared him to wear Tony's clothes to school for a day. Peter, not one to back down from a challenge, takes on the dare. He shows up at school in Tony's clothes, feeling a bit self - conscious at first but then starts to embrace the whole situation and even has some fun with it, like pretending to be Tony for a while.
Well, it could be really interesting. Maybe Peter would feel a sense of power or confidence that he associates with Tony. He might start to act more like Tony, adopting his mannerisms. It could also be a bit of a comical situation, like the clothes being too big for Peter and him looking a bit silly but still trying to pull off Tony's cool style.
One possible scenario could be that Stiles accidentally grabs Peter's clothes thinking they are his own. Maybe he's in a hurry to get dressed and doesn't notice until he's out and about. It could lead to some comical moments as people react to him wearing Peter's distinct style.
Perhaps in the fanfiction, McGee wears Tony's clothes as a joke among the team. The others initially laugh but then notice how different McGee looks and acts while wearing them. It could lead to some humorous banter and self - discovery for McGee.
Maybe Peter misses an important training session. Tony has probably put a lot of effort into training Peter to be a better superhero. If Peter skips out on training for something unimportant, like going to a party or just being lazy, Tony would be justifiably angry and yell at him for not taking his superhero responsibilities seriously.
Maybe in the fanfiction, Bella wears Edward's clothes as a statement. It could be a way for her to show that she belongs to him in a sense, or that she's part of his world. She might put on his shirt before going to meet his family, for example, as a sign of respect and acceptance of their relationship and his vampire lifestyle.
Peter might get mistaken for Tony. If Tony is popular or has a certain reputation, Peter could find himself getting the same kind of attention. Some people might come up to him thinking he's Tony and ask him about things that only Tony would know. This could lead to some really awkward or hilarious moments as Peter tries to either play along or quickly correct the misunderstanding.
Maybe Peter inherits Tony's high - tech gadgets. For example, he could get access to some of Tony's Iron Man tech, which would be a huge deal. This could set him on a new path in his superhero journey, perhaps allowing him to upgrade his own suit or develop new abilities.
One possible scenario could be for a disguise. Maybe Harry needs to blend in among Draco's group for some sort of undercover mission at Hogwarts. Another could be as a result of a magical mishap, like a spell gone wrong in a transfiguration class that swaps their clothes. Or perhaps it's part of a bet or dare within the fanfiction's plot.
Well, perhaps Ginny is trying to make Harry jealous by wearing his clothes in a fanfiction. She might put on his old Gryffindor scarf and walk around the common room, catching Harry's eye. Or, in a more adventurous scenario, Ginny has to disguise herself as Harry for some reason and has to wear his entire set of clothes, which leads to all sorts of comical and dangerous situations as she tries to act like him.
