Ah, leggings. Over the past few years, the stretchy trousers have dominated Kim Kardashian West's wardrobe and even taken over sales of jeans. While we've loved black, stirrup and cropped leggings, there's one type that has just taken a dive in popularity and another that's on its way up. According to retail analysts at Edited, traditional shops have upped their stock of plain and block-coloured leggings with a 29% increase at the end of 2017 in preparation for the upsurge in 2018. And if you're thinking that the athleisure trend is about to die, think again. Edited also revealed that activewear saw a 136% increase from 2016 to 2017, with predictions it's going to continue to grow. So while you can jump on Kim KW's sheer trend and stick to your favourite black leggings, we suggest you keep scrolling to see the best leggings to buy now.
