Hermione and Open
Hermione had been nervous when she'd turned up in the Great Hall, if only because this was certainly the least amount of clothing she'd ever worn around anyone in the school who wasn't her housemates. And she'd gotten looks. Lots of looks. So much so that she'd happily meandered her way towards the alcohol, and she really wasn't much of a drinker, but hey-
She slunk towards one of the corners of the hall, more regretful by the moment that she'd chosen to wear something so- what was the word, even? Well, she could go and change, but she wanted to see if Harry would turn up, and she wanted to see if he'd brought a date.
