Marc Jacobs for Louis Vuitton kick started this trend late last year and I instantly sat up and took notice. Anyone who reads this blog knows that I love comfortable, easy clothing and what could be more comfortable than wearing your PJ's during the day! I can't get over how gloriously chic Sofia Coppola looks in her head to toe Louis look; the classic navy pajama set with white piping is given a seriously sharp fashion edge with its leopard print and slim cropped cut. Add louche chic into your look and purchase the rather more affordable Rag and Bone silk PJ blouse www.barneys.com, wear with a skinny pant or a city short and a flat loafer and you will as look fashion fabulous as the glorious Ms Coppola.
