Sleeping on Sisi Silk helps your skin retain moisture, while protecting against hair breakage and frizz.Sisi features the same clean piping as our best-selling Savile collection, but in 22mm Mulberry Silk. Sisi has a subtle zipper closure to keep your pillow from escaping. About the print:Inspired by 17th-century French textiles and delicate garden trellises, this print sold out almost instantly when it was featured in our English Garden drop in February 2021.We got so many requests from Nap Dress™ Nation, we decided to bring it back and for the first time in a Sisi Pillowcase.
