As I write this post the weather outside is less than pleasant (I blame the good weather from the past few weeks for getting me excited for summer prematurely), which makes now the perfect time to start planning your sunnies before summer really begins. When it comes to shades, nobody does it quite as well as Nicole Richie and the Olsens and with that in mind it comes at no surprise that their respective lines, Elizabeth & James and House of Harlow 1960, are delivering some of the best styles this season.

Over the past year I've been sporting my tortoiseshell wayfarers but Richie's House of Harlow 'Chelsea' shades in black will definitely be my go to pair of sunglasses this year. If you're looking to make an investment the round-framed styles from Linda Farrow for The Row are equally as good, especially if you like the black version that Mary-Kate Olsen has been sported over the last few years. For more wallet friendly styles, head to Topshop who have very similar styles but for less than £30 or if the cat-eye is your shape of choice, Whistles do the perfect reinterpretation of Tom Ford's much loved frames.

Have you bought your summer sunglasses already?
