Sleeves are given a sculptural treatment in Roksanda's Resort 2018 collection, and this black silk-georgette Safiya blouse is a leading example. It's crafted in the UK with long ruched raglan sleeves that are bound to swing with every movement, and slashed on the inside to reveal alluring hints of skin. A high neckline and straight hem ensure a balanced finish. Slip it on over tailored trousers for a shapely contrast.
