It's impossible to talk about rollnecks and not think of Rollin', the classic Limp Bizkit track, so have a watch and listen, here. (Whoa! We'd forgotten all about the Stephen Dorff and Ben Stiller cameos.) Anyway, moving on. Rollneck jumpers are having a major renaissance. You'd be hard pushed to find an AW13 catwalk show that didn't show a rollneck in some form or another. The most exciting way to wear them was as a layering tool, worn under tops and poking out from cosy coats (seen below at Céline, Proenza Schouler and Victoria Beckham). And that's the beauty of it: they're the coolest thing in fashion right now but they're practical too - how often does that happen?
