Kate at the Cheltenham Festival in London on March 15
Loud cheers greeted the surprise appearance of the Duke and and Duchess of Cambridge at the races Friday.
Pregnant Kate, 31, sported a short camel-colored coat that covered her baby bump. She also wore her faithful Aquatalia brown suede boots and one of her favorite winter hats – the Lock and Co Betty Boop, which she donned to the close friend Mark Tomlinson's recent wedding in Switzerland.
As for her earrings, they were designed by Kiki McDonough, a favorite jeweler of hers. They are cushion-cut citrine diamond earrings from the jeweler's classic range, Eternal, and they retail for £1,200 (or approximately $1,800).
Kate wore diamond earrings from the designer on her first Christmas Day as a married woman in December 2011.
