In Carolina Herrera and Stella McCartney, respectively. This might be the best work Stella has ever done, and it's also possibly the best Amy's hair has ever looked.
And then, HOT DAMN. This dress is, like, revelatory on Tina. (It was slightly more raspberry on TV, even). She looks amazing -- so amazing that you don't even totally notice how amazing Amy ALSO looks. Whoever styled them for this event deserves a big fat juicy raise.
Cheers, you sexy bitches. You rock.
