As far as I know, a black peony does not exist, but if it did, I imagine it would look like this gown. The dropped waist, off the shoulder bodice has a ruched bust embroidered with black beads. The bubble skirt is made of chiffon petals. A black silk bow belt defines the waist.
This fashion fits Silkstone Barbie, Victoire Roux and FR2
