Hot girl summer is officially coming to an end, but that doesn’t have to mean ditching dresses. In fact, midi and long dresses can be a great way to keep some precious body heat on those chillier autumn days.

The key to surviving most British weather is layering, and this holds particularly true for autumn! You could be sweating it out by 3pm in your winter coat, or freezing at the bus stop on days when you leave your jacket behind. So getting layering right is absolutely essential, and luckily there are so many ways to layer a dress. You can try pairing it with tights, wearing it over a turtle neck jumper, or even chucking on a pair of knee-length boots for extra warmth.

From smock dresses to flowy dresses, we’ve hand-picked some of our favourites currently on offer this season at boohoo, PLT, I Saw It First, ASOS, Nasty Gal, Wallis and Dorothy Perkins. Plus, with a range of discount codes available, there’s no reason not to treat yourself!
