This has been the year of the it dress, as instead of handbags or shoes, it's dresses that are reaching cult status and selling out. There is a new style that is hard-to-track down — a sleeved knitted dress with a rollneck and dramatic slit on one leg by cult label Jacquemus. You'd be forgiven for thinking an ankle-length rollneck jumper would look a little frumpy, but it's surprisingly slinky thanks to the open slit. The dress comes in a red wine, rust and black colour, and it's hard to find any still in stock. Thankfully Zara is also embracing the knitted dress trend, if you can't find a Jacquemus 'Baya' dress. Keep scrolling to see how the fashion crowd is wearing the dress — and shop more.
