Newsweek has a new interview with Jessie Cave, who plays Lavender Brown.

You are totally festooned with bows, bangles, headbands, every Topshop accessory imaginable.
She’s a very girly-girl—she’s like the type of girl that you could imagine you could hear coming a mile off because of her bangles kind of rubbing together. She’s perfectly curled and coifed and ready to be seen at any occasion—very, very aware of how she looks. And very pink.

Are you like that in real life?
No, I’m definitely not as prepared as she is, and I’m definitely not as neatly intact at all times. It was a major decision to make her hair curly, and to make her very pristine. The headbands are something I wear in my life, too. But I’m definitely nothing like her; I wear glasses in real life and have a bit of a beak.
