Kate Middleton and Meghan Markle are two people we often look to for royal style inspiration, but don't underestimate the York sisters' abilities.

Princess Beatrice, the eldest, just went to the Chelsea Flower Show in London (a favorite royal event) with her husband, Edoardo Mapelli Mozzi.

The royal family chose an ankle-length white and blue floral dress by sustainable label Reformation for the occasion, which featured three-quarter-length puff sleeves, a nipped-in waist, and an elegant slit down one side of the skirt.

The best part' Bea's off-the-rack pick can still be purchased online directly from the brand - or check out some similar models for all your hot girl summer needs.

Beatrice paired her summery number with black strappy shoes and a small black basket bag. The entire look.

Also at the RHS Chelsea Flower Show (opens in new tab) - the annual floral bonanza at the creative garden showcase - the Queen herself dazzled in a Barbie pink floral dress and pearls...

... The Earl and Countess of Wessex chose simple white dresses...

... Princess Alexandra in a more subdued shade of pink...

... Prince and Princess Michael of Kent.

A truly royal affair.
