Mischa Barton at Georgina Chapman for Garrard Collection Launch

Mischa Barton was spotted looking beautiful in black at the Georgina Chapman for Garrard Collection Launch event held Oct. 27 in New York.

Mischa is wearing a black one-shoulder Notte by Marchesa dress with a chiffon overlay and embroidered waist detail. (Check out the Marchesa website – I love looking at all of these evening wear selections!)

Mischa also is wearing a gold and white diamond bird wraparound Gerrard ring.

Pictured in the photo below is Mischa with British designer Georgina Chapman and model Helena Christensen. Chapman is wearing the electric blue strapless Marchesa dress.

In 2008, it was announced that Marchesa designer Georgina Chapman would be a guest designer for classic jewelery house Garrard.
