Royal blue is fashion’s favourite colour flavour this month, all thanks to Kate Middleton’s sold-out Issa dress and spring’s bold brights – and if you’re looking to spice up your winter wardrobe, there’s no better way than with a cool cobalt frock that’s fit for a modern day style Queen.

We love Tibi’s draped silk dress from Matches – with its sophistictaed Grecian design and flattering folds of fabric, this classic piece gets the royal seal of approval, but at £345, you might need a princess’s budget to go with it.

If you can’t afford to splash the cash, royal favourite Reiss has come to rescue with a low-cost alternative. In a strikingly similar statement blue with a wrap-around design, this timeless figure-hugging bandage dress will make you a Middleton in no time.

Whichever classic cobalt you choose, we’re sure Kate will approve.
