I really like how they are all dressed like their characters in this photo.
Katie has a sweet flowery dress, smart looking enough but nothing too fancy.
Dan do what you’re supposed to do as the headcharacter and puts on a suit (even though he didn’t want to).
Emma also dresses a little “fancyer” and has a nice dress proper for her age and really nice shoes. And she doesn’t put on a jacket even though it cold, because you’re not supposed to have one with this dress so I will freeze.
Rupert doesn’t seem to care that much (or know) that you might be supposed to wear a suit, or maby he just doesn’t own one.
And Evannna. Evanna doesn’t really give a fuck about the dresscode and puts on comfortable clothes and vans, and if someone asks she just shrugges and answer “I think I look pretty”
