I love them. They're cute, easy-ish to do once you get used to it, and although my hair's fairly short, I can still do them! I like the messy way Drew Barrymore has hers, and that's sort of how mine was today, mainly because I'm not super at it... yet!
I like the simpleness of Jennifer Aniston's between her parting. Peaches Geldofs' is really nice. It's nicely styled and the hair accessories work with it really nicely. Sienna Miller's is almost like a halo and looks good with her Grecian style dress.
I'm going to keep practicing, I want to be able to do this perfectly!!
