i think eva green had the best dress. the colour perhaps did not stand out, but the cut was great and she looked simply divine in it. i also liked the simplicity of emily blunt's dress.
i was looking forward to cate's dress, but it wasn't exactly something i was hoping to see. she HAS looked better imho.
as for beyonce's dress - dear god! i believe she ruined that one for me, because the dress itself was stunning. it would have looked much much better on someone skinnier with very pale skin and with very blonde hair or dark hair.
