PARTY TIME: The Kate Middleton-approved Italian fashion label Alessandra Rich on Monday dropped an exclusive capsule collection for Net-a-porter inspired by the idea of a sun-drenched, joyful, and a little mischievous summer party.

The release coincides with the beginning of London’s summer party social calendar, with highlights including the Royal Academy of Arts’s summer exhibition preview party on Tuesday, and the legendary Serpentine summer party on June 24, as well as the Royal Ascot horse races, slate for June 17 to 21.

Alessandra Rich, founder of her namesake label, said the range, which includes a total of 15 cotton and silk dresses in delicate prints, is a celebration of femininity with a modern twist of glamour, and is made to be worn from morning to midnight.

Kay Barron, fashion director at Net-a-porter, said Alessandra Rich continues to “perform exceptionally well, with her romantic silk dresses emerging as standout favourites.”

“Their enduring elegance, paired with the brand’s signature mix of softness and edge, resonates strongly with our audience and is a firm favorite among our EIP clients of all ages, who appreciate the flatter atmosphere and feminine silhouettes,” added Barron.

The Princess of Wales has worn Rich’s design multiple times.

Last month, she wore a flowing black and white polka dot dress for the Thanksgiving Service to mark the 80th anniversary of VE Day at Westminster Abbey, the site where Middleton and Prince William wed in April 2011.
