Anna Williamson and Ella Ringner, founders of luxury nightwear collection <b><a href="http://www.selfridges.com/cat/yolke/" style="text-decoration: none"><font color="black">Yolke</font></a></b>, designed the <b>Zigzag pyjama set </b>with comfort and longevity in mind. This lustrous pure cotton duo is classically cut; the shirt&#39;s directional zigzags highlight the lapels and chest pocket as the softly streamlined trousers can be brought definition with silk ties at the waist. A touch of stretch allows for effortless fluidity of movement.
