Queen of mixing high- and low-fashion, Kate Middleton ended her summer of floral dresses with one of her best yet, and wore it with an inexpensive pair of dangly earrings.

The duchess wore a baby-blue Emilia Wickstead floral midi dress ($2,255) with her go-to taupe espadrille wedges by Monsoon ($65) and $10 gold filigree earrings from Accessorize as she showed off her garden design at the RHS Garden Wisley in Surrey, England.

The Duchess of Cambridge laughed and joked with celeb chef Mary Berry, former host of The Great British Bake Off. The two even rode around on a tractor trailer.

The mother of three gave a speech for the event: “I was passionate about creating a garden that inspired children and adults alike to get back to nature and reap the positive mental and physical health benefits that it can bring.

"As a parent, I have learned just how important it is to foster our children's development, in all areas, not just physical, as soon as they're born," the duchess said.

Middleton's seersucker dress featured a matching belt at the waist and two breast-pockets, and we're loving the old-school "Sloane Ranger" vibes reminiscent of Princess Diana in the '80s.

Florals in September? Does this mean we have royal permission to wear them all autumn long? (We think that's a resounding "yes.")
