Designers kicked off the seasonal catwalk shows this week in New York, with brands including Khaite and Michael Kors showcasing their autumn/winter collections to an audience of buyers, press and VIPs such as Amanda Seyfried, Martha Stewart and Greta Lee.

Fashion was at the forefront, obviously, but beauty looks were also key. The standout hair trend from the week was the ‘undone bob’, which was spotted on several major catwalks but also off the catwalk, as Sofia Coppola, Isan Elba and Tory Burch showed off their hairstyles.

At Prabal Gurung, hairstylist Lacy Redway partnered with Tresemme for the show, showcasing looks that were all about an undone, lived-in texture. “They say the best nights leave the best hair – effortless, playful and full of attitude, like you rolled out of bed after a party and went straight to the runway,” explains Redway.

The ‘undone bob’ got a party-meets-preppy update on and off the catwalk at New York Fashion Week
