We're used to seeing her step out in designer looks fit for a royal – but Kate Middleton proved she can also dress down stylishly too.
The Duchess of Cambridge, 39, turned to the high street for her relaxed outfit to receive her COVID-19 vaccination.
In an image shared on Instagram, the mother-of-three could be seen wearing a white cap-sleeved, ribbed top and blue slim fit jeans while being given her first jab at London's Science Museum on Friday.
A short statement captioning the image read: "I’m hugely grateful to everyone who is playing a part in the rollout - thank you for everything you are doing."
The post has received more than one million 'likes' and over 7,000 messages – many of which praised the duchess for getting protected.
Several noted that, despite her off-duty ensemble, she still looked "glamorous" and "pretty".
One person wrote: "Yes to science and yes to this jeans and tee look."
Another shared "love the outfit", and a third joked "ok but where are your jeans from".
According to Hello!, the top worn by the duchess is from H&M, while her jeans are from & Other Stories.
Both high street chains are part of the H&M Group, which also owns COS, Monki, Weekday and ARKET.
Prince William's wife finished off her look with a voluminous blow-dry, natural make-up and a blue face mask.
It came after the Duke of Cambridge received his first jab at the same location over a week ago.
Earlier this week, the duchess deliberately dressed "like a princess" to surprise a brave cancer patient.
She slipped on a £450 frock from brand Me + Em in pink – the favourite colour of Mia Sneddon – to visit the four-year-old at the Palace of Holyroodhouse in Edinburgh during a tour of Scotland.
The royal accessorised with a suede pink belt by Boden, which currently costs £38 from John Lewis, as well as a pair of Rhodochrosite Gold Mini Pyramid Charm Hoop earrings from Missoma.
