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, this season sees the return of favorite silhouettes in the same Bondi Beach inflection that made the label a hit. This unadorned 'Esther' dress has a snug fit with a strapless neckline and mini hem. Wear yours with sandals and a contrasting leather bag for an effortless resort look.
