An acronym for “separates, intimates and ready-to-wear,” SIR equips the modern woman with effortlessly feminine staples. It's a brand born of wanderlust and a want for effortless style, so its pieces belong as much in a suitcase as in the everyday wardrobe.

Drawing inspiration from the Australian coast, best friends Nikki Campbell and Sophie Cootewhat started with an online-only capsule collection that has quickly grown into an expansive selection ranging from dresses to two-piece suiting. From beach to boardroom, SIR has you covered with a new standard in essentials.
