These black and white Olivia von Halle Lila Nika striped silk pyjamas are shaped for a relaxed fit with all-over stripes. With contrast piping, the shirt features a notched collar, mother of pearl buttons and long sleeves, while the trousers have an elasticated back and full-length legs. They say the course of true love never does run smooth. But that was before we met this Olivia von Halle pyjama set – now it runs as smooth as silk.
