With a shared love of '70s style codes, friends and co-founders Nikki Campbell and Sophie Coote launched SIR (or Separates, Intimates, and Ready-to-Wear) to craft the pieces they want to see in their own wardrobes from matching sets to dream cover-ups and floaty separates. Cut from a crisp linen-blend, the 'Dorian' pants are a simple, wide-leg silhouette designed to sit low on the waist and button at the side.
