References: Russian ball gowns & patterns

Sorry this will be a quick post, middle of the night here. 

For this painting I was mostly looking into traditional Russian dress, in specific the 1903 Ball in the Winter Palace for the lovely ballgowns. Ever since watching someone play the Witcher 3 I've got really into traditional European costumes...though more on the extravagant end.  

Yes, that is my little chubby child hand.

I'll edit in proper references to where I found everything in the morning.... *yawn*
