The Duchess of Edinburgh continues to prove she is a master of effortless summer dressing – and her elegant cotton floral dress from Erdem is no exception.

During her visit to the Kent County Show on Friday, the royal, 60, stepped out in a designer shirt dress by the British fashion house. The frock featured a bold botanical print in shades of burgundy, red, forest green, sky blue, and ivory.

Shirt dresses are one of Sophie's go-to styles, and this one is a striking example. With a fit-and-flare shape and three-quarter sleeves, it's a flattering, easy-to-wear look. Sophie completed her outfit with neutral espadrille wedges and a tan clutch.

While her exact piece is from a past season, the Daily Express has rounded up a selection of floral-patterned shirt dresses from the  high street – including a beautiful option from Boden, currently on sale.

This vibrant A-line green shirt dress from British high street favourite Roman is made from crisp poplin cotton like Sophie's frock. Its short sleeves and relaxed fit give it a slightly more casual vibe, though there is a matching belt to cinch in the waist if you want more definition. Currently on sale with 20% off, it's available in sizes 12 to 20.

This pretty floral dress from Crew Clothing is crafted from a cotton-blend fabric and is shorter than Sophie's dress, falling just below the knee. Take a leaf out of Sophie's book and style with espadrille wedges and a coordinating clutch. It's available in sizes 6 to 18. 

If you prefer your shirt dresses a little shorter, this option from Boden is a chic alternative. Crafted from 100% cotton, it features a floral-inspired print with a smock neckline rather than a shirt collar. You can either tie it at the waist with the matching belt or leave it loose. It's available in sizes 8 to 22 and also comes in petite, regular, and long lengths. There are alternate colours to choose from too, including a vibrant pink variation.
