Duchess Meghan Markle stuns in Oscar de la Renta for Princess Diana's niece's wedding

Just a few weeks after their own wedding extravaganza, Duchess Meghan Markle and Prince Harry stepped out for another notable nuptial. The Lincolnshire, England for the wedding of Celia McCorquodale, Princess Diana's niece, and George Woodhouse.

The bride wore the Spencer tiara, which is the same tiara Princess Diana wore at her own wedding in 1981.

For the event, Meghan donned a gorgeous blue floral Oscar de la Renta wrap dress from the designer's Resort 2019 collection. The Duchess of Sussex paired the long-sleeved cocktail gown with a white Marks & Spencer fascinator, white Aquazzura heels and a white Carolina Herrera Scala Insignia clutch.

The gown, which retails for a hefty $5,490, worked perfectly for the summer's high society wedding -- though many were quick to criticize the size of the dress, with many asserting it "swamped" Meghan.

It's been a big few weeks for the royals, who celebrated Prince Philip's 97th birthday and the Trooping of the Colour. Most recently, the new Duchess shared a few giggles after stepping out in Cheshire for her first solo engagement with the queen.
