When it comes to trends, there's always one piece each season that works the hardest and gets turned into outfit after outfit on your Instagram feed. Last year the must-have piece was the famed wrapover skirt with its soft ruffles and a laid-back look. This season, there's another midi skirt that's cropping up all over our feeds, not to mention on the streets of Fashion Week. We've all been swapping our soft wraps for simple bias-cut satin skirts. The slinky style looks as good with a jumper and trainers as it does dressed up with a crop top and heels, and you'll find no shortage of different colours and prints this season. Topshop's sleek number comes in dozens of variations and has become the high street's ultimate must-have, but ASOS isn't far behind with plenty of alternative options. Check out our gallery of outfit inspiration ahead, then pick your favourite colour and shop the skirt for yourself. It might be one skirt, but it works seriously hard.
