Anoushka is wearing an outfit from 1926 Vogue, Lubochka in a hat, earring, cigarette ensemble from 1920 Vogue, and Olegushka in a partial suit from Esquire I thought looked smahhht.
Anoushka is wearing a Vivienne Westwood outfit, Lubochka an Alex and Chloe dress, and Olegushka in an Alex and Chloe shirt. I bet they were feeling really original when they designed that one.
