Fashion is staying in the realm of nostalgia, with denim the must-have trend of the new season. It’s not just the enviable street stylers of Instagram who are showcasing the veteran fabric. From Prada to Victoria Beckham, denim is having its moment on the catwalk. During the past few seasons the blue siren has been sneaking in through the trends of dungarees, double denim and the forever sibling rivalry of skinny jean versus boyfriend, girlfriend and flares.

This season, however, denim which is potent symbol of youth and rebellion is all grown up by making a move away from the distressed feel of the grunge era. It’s time to take the perennial trend seriously. Meanwhile, designers tap into our love of all things nostalgic, they have reinvented this most hardworking of fabrics making it fresh for the 21st century.

Giving denim the ultra seal of fashion approval is the socialite, street style star and all round uber fashionista Olivia Palermo. In keeping with the seasons fresh approach, Palermo’s collection gives the traditionally casual material a more formal feel, she used it to create a high-waisted midi skirt with a centre slit, a tailored jumpsuit, aka dungarees, and a pair of wide-legged cropped pants with a braided waistband.
