Hermione was feeling incredibly self-conscious in her Snow White Costume. She knew she shouldn't have let the fellow at the costume store dress her in whatever he wanted. This costume was a little skimpy. She spent a good portion of the time she was in it running her hands over her backside, wishing the skirt was a little shorter. But she kinda liked the way her legs looked in the thigh-high tights.
She saw Percy come in from where she was standing near the refreshment table, nibbling on the muffins that Audrey Baxter brought for the party. When Percy looked like he was a little more settled, Hermione approached with a smile. "Hey, Percy."
