I thought these 3 lines for Resort 2011 should deserve some special mention:
1) Balenciaga:
Fantastic use of prints & colour in alien-like combinations that only Balenciaga could come up with.
2) Vena Cava:
Girly vacation style, for lack of a better word: very refinery29.
3) Jason Wu:
Somehow I can just imagine Michelle Williams wearing this- very pretty, clean and feminine.
