PRADA

Brand-plaque drawstring-hem skinny-fit slim-leg Re-Nylon trousers

Prada doesn't just do formal tailoring – the Milanese namesake is also something of an expert at relaxed pieces like these elasticised-waistband trousers. First, they're spun from recycled yarn obtained from plastic recovered from the ocean (that's Re-Nylon to you and me). Next, they're cut to a skinny-fit, slim-leg silhouette and topped with a handy drawstring hem. The small zip pocket at the right hip is ideal for stowing away your earphones.
