“Sienna’s gown is a design based on our Honor silk slip dress, inspired by the understated minimalism of the ’90s,” says its maker, Savannah. “Sienna has a unique vision and the ability to be brave and bold in her fashion choices, so when she requested this in a burnt tangerine colorway for a red-carpet event in 2018, it was thrilling. This piece is a timeless classic and its versatility made it perfect for an elegant summer wedding.”
Sienna flexed her creative muscle (the pair ran cool London label Twenty8Twelve in the Noughties together) once again when it came to her sister’s wedding in December 2022. She commissioned Savannah to make her an ice-blue velvet version of the Savannah Miller bridal Cerise dress: a cowl-neck, spaghetti-strap number with a scooped back and elegant train. Instead of the flowing lengths, Sienna ordered a chop to make it even slinkier. “It’s effortless, it’s sexy, it’s ’90s–all the good words,” Savannah told Vogue just 48 hours before her Petersham Nurseries nuptials, when Sienna was yet to fly in from New York and try on her bespoke mini. There was zero worry in the atelier: “There’s only a certain number of people who can get away with these looks, and Sienna is one of them.”
