One scenario could be after a big Quidditch match where Draco's team wins. Hermione, in a moment of celebration and a newfound sense of unity among the houses, puts on his jersey.

Or maybe in a magical prank gone wrong that results in a spell binding them in some way, and as part of the chaos, Hermione ends up wearing Draco's jersey.
One possible scenario could be during a battle at Hogwarts. Maybe the Death Eaters target her specifically, and she gets hit by a dark curse while trying to protect her friends.

One consequence could be a loss of status. In the wizarding world, Quidditch players are often quite popular and respected. So, Draco would lose that social standing. For example, his friends who were into Quidditch might start distancing themselves from him.
