Online men's retailer MR PORTER has announced a collaboration with fashion brand COS to launch The Modern Traveller, a capsule collection for summer. The limited edition 23-piece collection offers a selection of menswear essentials in seasonal greys, burgundies and hues of navy. Key pieces include the slim-cut tailoring in classic single-breasted styles, available in deep navy and burgundy. The sharp silhouette is also prevalent in the outerwear pieces and shirting; with clean lines and grey tones representative of the stark architectural inspiration behind the collection. The Modern Traveller Collection will launch on 7 May on MRPORTER.COM/COS and in selected COS stores worldwide.
