My favourite is definetely Rachel Bilson, she looks beautiful with her hair up and the print of the dress and boots look great on her. I can't decide which Alexa Chung look I like more, but I'm leaning more to the long white skirt.
I don't think it's out in America yet, but Tamara Drewe is fantastically funny, British and sweet. Gemma Arterton is gorgeous and brilliant as always, Tamsin Greig makes you cry and Luke Evans makes you - well. He looks good that's all I can safely-PG-rated say.
