Indeed there is full version of this picture, but I posted it here cause the quality was quite good.
If we talking about all those costumes from that ball in 1903 - I like especially this one in which Andrei Vladimirovich was dressed. Misha had also splendid one (poor Mishkin, he lost a diamond clip in the cap that nightXD).
Tsar and Tsarina had in my opinion the worst costumes of all.
