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. This silk maxi dress is defined by a high-collar bodice and a clean, elongated silhouette. A straight-cut skirt is finished in a contrasting print that adds visual depth to the streamlined form.
