Ksenia Bradner in Alexandra Vidal Fall 2012

Ksenia Bradner was flanked by the hosts David Furnish and Elton John on a sunny evening in Windsor, England, for the 14th Annual White Tie and Tiara Ball to Benefit Elton John AIDS Foundation.

Taking the dress code very seriously, Ksenia looked stunning in a sapphire Alexandra Vidal Fall 2012 strapless bustier ostrich feather gown.

She completed her look with a chic updo, a Judith Leiber "Spring Fling" minaudiere, Jimmy Choo "Lake" sandals, pink lipgloss and Tiffany jewels.

I love her peacock feather diamond bracelet.
