We're taking a lesson in versatility from mix-master queen, Alexa Chung. The Chungster worked a playsuit two days straight, managing to make her overall onesie work for both trotting around the streets of Paris during Haute Couture Fashion Week, and hanging out at London's Wireless music festival. Clever, non? So, how'd she do it? With a little accessorizing nous and a knack for layering, that's how! Both of Lex's playsuits have a utilitarian vibe, which we think helps to transcend the usual dress code parameters. A striped tee, floppy felt hat and canvas carry-all made it Parisienne appropriate, whilst her leather biker jacket, platform sandals and designer tote helped to toughen the look. After Alexa's lesson in versatility, we're investing in this one-piece wonder. Now, the only question is will you buy-up in denim, or black? Or both?
