About SIR the Label

SIR the Label is an Australian label founded in 2014 by Nikki Campbell and Sophie Coote. The name stands for Separates, Intimates, Ready-to-wear, and the house now has a flagship in Bondi and stores in Sydney, Melbourne, Brisbane and Perth. Its look is relaxed and grown up: silk slip dresses and bias gowns, linen and cotton for summer, sharp tailoring in wool suiting, fine knits and a swimwear line built on prints that run through the whole collection. SIR designs to its own 0 to 4 sizing, which Coveti shows on the UK ladder so you can choose with confidence.

“The Ari Reversible Tie Triangle Top is the kind of bikini top I reach for again and again. Quiet, but it always looks considered.”

Gemma Deeks, Fashion Editor at Coveti
