who is stylish in hp?

Hmmm. I'd have to say Lucius Malfoy. He is wealthy and carries himself as such, however snobby he may be :P

I think, Luna Lovegood is the most stylish character in Harry Potter. She's not that visible during the first books but she's been one of the interesting character in the Deathly Hallows for me. She seemed weird at first but she gently transformed into a lovely lady eventually. I think she caught my attention as she's the only one not wearing the school uniform on the last part of the Deathly Hallows.
