A great idea could be a time - travel fanfiction. Hermione accidentally travels back in time to Draco's childhood. She has to blend in, so she borrows some of his clothes. Draco, as a child, is curious about this strange girl in his clothes. This interaction could change the course of their future relationship in the original timeline.
In a fanfiction with this theme, it could be set post - war. Draco and Hermione find themselves in a situation where they are on the run from some dark wizards who are after them for different reasons. During their escape, Hermione gets wet and cold. Draco, having a change of heart after the war, gives her his warm cloak. This act of kindness begins to break down the barriers between them, and they start to have deeper conversations, realizing they have more in common than they thought.
She might wear his clothes because of necessity. For example, if her own clothes got damaged or lost during an adventure. Harry's clothes would be readily available and a practical solution.
One reason could be that they are in a situation where they need to disguise Hermione as Fred for some sort of mission. So she has to wear his clothes to blend in. Another possibility is that it's a symbol of their closeness. After a particular adventure where Fred saved Hermione, she wears his clothes as a sign of gratitude and a growing bond between them.
Maybe it could be a story where Hermione is cold and Fred offers his clothes. Then it becomes a cute moment that leads to a deeper friendship or some unspoken feelings between them.
One interesting scenario could be that Hermione wears Harry's clothes during a secret mission. It might add an element of disguise and also show a new level of closeness between them. Maybe she has to quickly put on his clothes to blend in with a group that is expecting Harry.
Another reaction could be confusion. Draco might not know how to feel. On one hand, he has his Slytherin pride and his clothes are part of that. But on the other hand, seeing Hermione in his clothes gives him a strange feeling in his stomach. He might end up being more curious about Hermione and her reasons for wearing his clothes.
Perhaps in the fanfiction, there's a school event where they have to swap clothes as part of a charm challenge. Hermione wearing Draco's clothes makes her see the Slytherin world from a different perspective. She might notice the small details in his clothes that reflect his status and family, which could lead to a deeper exploration of the Slytherin - Gryffindor divide.
The phrase 'take off your clothes' in the context of fanfiction is inappropriate and goes against ethical and respectful content creation. Fanfiction should be about exploring characters and stories in a positive and non - exploitative way. Hermione is a well - known character from the Harry Potter series, and she should be respected in fan - created works.
