Angelica Ardasheva of Angy's Tea Room, after A Show, Paris, October 2014.
I have a vase of stunning white hellebores in front of me (Helleborous Niger, the Christmas Rose) and they reminded me of this lovely white backless dress Angelica wore so beautifully.
I think this might be a beautiful Vita Kindress? In any event, I love this. Fab with flat sandals for a daytime, beachy vibe and with heeled wedges or sandals for evening.
