Kate Middleton's style has been compared to Princess Grace of Monaco's before, as they both wore lace wedding gowns
The royal mom joined Queen Elizabeth, Prince William and other members of the royal family at the annual Diplomatic Corps reception at Buckingham Palace on Wednesday evening. Although she usually opts for light-colored gowns for such occasions, Kate stunned in a blue velvet dress with long sleeves by Alexander McQueen (her wedding dress designer!).
The dress immediately drew comparisons to another royal: Princess Grace of Monaco, formerly Grace Kelly, who wore a very similar look. Although Grace’s dress lacked Kate’s long sleeves, the gowns had nearly identical sweetheart V-necklines that give an off-the-shoulder feel and glam appeal.
Both royal women also rocked statement drop earrings to complement their ensembles. Kate wore her hair in an elegant updo, showing off her statement earrings and necklace, the Nizam of Hyderabad necklace which she previously wore in February 2014.
Of course, Kate did add an extra touch of sparkle to her look: the Cambridge Lover’s Knot tiara, a favorite of Princess Diana’s that Kate has worn on several occasions over the years.
This isn’t the first time Kate emulated Princess Grace’s style. Many saw similarities between the Duchess of Cambridge’s bridal gown from her 2011 wedding to Prince William with Princess Grace’s wedding dress from her 1956 nuptials. Both dresses featured a lovely lace bodice and full skirt.
The royal parents were helping Queen Elizabeth, who chose a gown by her go-to dressmaker Angela Kelly and the Vladimir tiara with emerald and diamond drops, host a special reception for diplomats at Buckingham Palace.
The evening party is one of the highlights of the royal year and a pre-Christmas tradition. The Queen, 93, hosts around 1,000 guests for the white tie bash.
Men wear tailcoats and women are in long gowns as the party moves through several of the magnificent state rooms of the palace including the State Dining, the Blue Drawing and the White Drawing rooms.
