Naomi Watts 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, Naomi looked stunning in a Marchesa gown that was similar to Look 5 from the Fall 2012 collection.

Her gold-embroidered crane gown had a delightful princess-like frothy tulle flared skirt.

We objected to her overwhelming necklace worn with a Marchesa gown during Cannes Film Festival, but on this occasion her Chopard triple-strand white diamond necklace and white diamond cuff were the perfect complements.

The look was complete with a fresh-faced look and chic updo.
