Meghan Markle Wears Club Monaco Dress and Philip Treacy Hat at Prince Harry’s Friend Charlie van Straubenzee’s Wedding

Meghan Markle and Prince Harry are back on the wedding circuit again today, arriving in style for Harry’s close friend Charlie van Straubenzee’s wedding to Daisy Jenks. Meghan wore a sophisticated Club Monaco black dress with green and pink in the pleated skirt and a black Philip Treacy fascinator with Aquazzura heels. Pretty, classic, and princessy.

The dress is still available for $328:

This additionally marks Meghan’s first birthday as a royal—and first time making a public appearance as a duchess during it. Meghan turns 37 today.

This is also her second wedding this summer since her own. Meghan and Harry previously went to his cousin (the late Princess Diana’s niece), Celia McCorquodale’s wedding to George Woodhouse in June. Meghan wore a blue floral Oscar de la Renta dress then.

Van Straubenzee attended Meghan and Harry’s wedding in May and was believed to be an usher at the ceremony. He became friends with Harry at Ludgrove Prep School as kids, according to Hello!. He’s also close to Prince William, and his own older brother, Thomas van Straubenzee, is Princess Charlotte’s godfather.
