SIR, an acronym for Separates, Intimates, and Ready-to-wear, is an Australian contemporary fashion house founded by Nikki Campbell and Sophie Coote in 2014. The duo identified a gap in the fashion market for timeless basics that could travel effortlessly from destination to destination while living in Bali, though the brand originated from their apartment in Bondi Beach. What began as a desire to create minimal, elevated pieces that could be easily packed in a suitcase has evolved into an internationally acclaimed brand. SIR has garnered international acclaim for its singular aesthetic centered on wardrobe essentials and minimalist silhouettes. With a focus on high-quality, ethically sourced fabrications, the brand creates easy-to-wear wardrobe staples that embody modern femininity with effortless elegance. The collections balance sophistication with wearability, appealing to women who appreciate understated chic and versatile pieces that transition seamlessly from casual to elevated occasions.
