Marks & Spencer just launched the most epic collection of summer dresses

While now might not feel like the perfect time to be discussing summer fashion - what with the British weather seemingly malfunctioning in a big way - we've heard vague whispers of brighter skies from the end of next week and that's just enough temptation to see us - perhaps naively - planning our new season wardrobe. No, we don't take much persuading...

In typical fashion, Marks & Spencer preempted our renewed interest in fair-weather dressing and took it upon themselves to drop one of their best ever summer dress collections earlier this week.

Bursting with chic midis and super fun minis, this is truly one of those collections that is not only universally flattering but also utterly timeless. With staple animal and floral prints running through the punchier pieces and classic broderie anglaise and shirring adding accents to the subtler ones, these are dresses to have now and to hold onto for years to come; forever the key when it comes to shopping sustainably.

M&S, who ensures that 100% of the cotton for its clothing is now more sustainably sourced via the likes of Fairtrade, organic and recycled fabric, has long been a stalwart for high street hits (remember the suede skirt and that pink coat?), and it seems this summer there'll be more than one sell-out successes.

If you're looking for a super easy throw-on number complete with that chic effortlessness we all strive for, may we direct you towards the white embroidered midi, the pink floral v-neck number or the sleeveless black midaxi that would go with almost every shoe you already own.

If you want something a little more formal - perhaps for a return to the office or for a friend's wedding - look no further than this green floral print high-neck midi if you still want to make a statement, or the brown belted polka dot dress for something a touch subtler. And remember you might be able to save on your purchase with these Marks and Spencer discount codes.
