Founded in 1998 by Rei Kawakubo's protégé Chitose Abe, the Sacai collection is a clever mix of whimsical hybrids, voluminous silhouettes and contrasting fabrics. Grey wool paper bag waist trousers from Sacai featuring a button and zip fly, a drawstring waist, two back buttoned welt pockets, a tapered leg and elasticated ankle cuffs.
