"Casual" might not be the first word that comes to mind when you think of Britain's royal family. Good thing Kate Middleton is around. When she's not reusing her favourite designer dresses or donning her Betty Boop hat again and again, the Duchess of Cambridge favours sportswear and messy buns like the rest of us.
Over the years, Middleton's no-fuss looks have been low-key majestic as her glitzy outfits took centre stage.
Dressing up or down, here are a few looks where the royal was the epitome of chill:
When Kate went all black everything.
And then all plaid everything.
When Kate gets in uniform when duty calls.
When Kate knows to dresses appropriately for long hikes.
When Kate pulls out the joggers to fool around.
When Kate gets stripey over a game of polo.
And when she repeated the stripes look while playing volleyball.
Back at it again with the stripe shirt.
We're not joking, she really loves this shirt.
