While they've been known to experiment with modern and more edgy styles on nights out, Princesses Eugenie and Beatrice know the importance of dressing to suit the occasion.
So the sisters, who regularly win praise for their elegant sartorial choices, both stepped out in rather classic ensembles as they joined their father Prince Andrew and other key members of the royal family at Easter Sunday service.
Eugenie looked chic in a cobalt blue dress that perfectly matched her skin tone, and a co-ordinated white beret and jacket.
Meanwhile her elder sister Beatrice impressed in a floral print frock and navy blazer and an incredibly ladylike ivory-hued pillar box hat.
Also attending the service at St George's chapel, Windsor Castle, were the Duke of Edinburgh, the Queen – a vision in regal purple – Sophie, Countess of Wessex and Princess Anne.
Beatrice has recently spoken out on the subject of living in the royal spotlight, suggesting that her sister in particular would prefer a life without so much fuss.
"I think if Eugenie could have any other life than the one she currently has, she'd definitely choose one without cameras, without photographers and generally one where she could blend into the background," she told the Daily Mail newspaper.
"We were born into this life and we understand that, but it is a little difficult at times."
She continued: "I think Eugenie feels a little hounded when she's forced to pose for pictures and she's really just wanting to have a privately fun time. I suppose I agree with her on that one.
"I can understand how she feels, because sometimes the interest is such that it becomes too intense and people have said some nasty things about us."
