Marks and Spencer's 'elegant' £59 summer dress looks just like Kate Middleton-approved sell out £280 Zimmerman version

Kate Middleton is known for her impeccable style, earning the top spot as the best dressed royal years ago. The Princess of Wales effortlessly dresses for the occasion, opting for high-end frocks from the likes of Jenny Packham, Alexander McQueen and Preen on the red carpet and at glamourous royal engagements, and more casual picks from the high street at more everyday affairs.

While Kate has stepped back from royal duties at the time being, we've been thinking about some of her best looks from over the years, including a white Zimmerman number that she wore while on official trip in Australia over at Easter in 2014. The timeless £280 broderie dress sold out years ago, but we've noticed a similar version that is available to buy right now from Marks and Spencer - and it's much cheaper than the original version.

Marks and Spencer's Pure Cotton Broderie Midi Shirt comes in at £59 and is a dead ringer for Kate's frock. It comes in petite, regular and long lengths, as well as in sizes eight to 24. The Pure Cotton Broderie Midi Shirt has been constructed from 100% cotton that is both lightweight and breathable, being perfect for the British summer and for any holidays that you have planned this year.

The shirt dress has been cut to a regular fit, with a flattering tie belt at the waist. The collared neckline and short puff sleeves lend the piece lots of smart appeal, being perfect to wear to the office or dressier events, while the broderie fabrics adds a pretty touch.
