Princesses Beatrice and Eugenie took their husbands to lunch in Mayfair amid calls to step up for the Royal Family.
The daughters of Prince Andrew and Sarah Ferguson were joined by their husbands at the upmarket Audley pub in Mayfair.
Princess Beatrice, 35, wore a new midi cream dress from Self-Portrait, which cost a whopping £450.
The Princess of York had clearly altered the skirt length to make it shorter to enjoy the warm May heat.
For footwear, Princess Beatrice donned Chanel slingback pumps which retail for £910.
Her younger sister Princess Eugenie, 34, wore a Diane Von Furstenberg midi dress in a berry shade, which cost £430.
Jack Brooksbank's wife accessorised with a tan clutch from Mark Cross, retailing for £1,750.
In addition, Eugenie wore £650 suede heels from Gianvito Rossi.
The sisters' outing in Mayfair comes as royal commentators have called for Beatrice and Eugenie to step up for the Royal Family, especially amid Princess Kate's absence from duties.
Princess Beatrice, in particular, is expected to play a more prominent public role for the Royal Family this summer.
According to reports in The Mail, Buckingham Palace is still considering how best to deploy Beatrice, but she is expected to accompany the King to one key event, possibly the Japanese state visit next month.
A source told the publication King Charles wants Beatrice to appear at events, as well as occasionally her sister, Princess Eugenie, who is also a non-working royal.
The insider said: "They've got a busy diary coming up and they need to widen the family at social events. You've got a whole week of Ascot.
"You have four garden parties. You've got Trooping the Colour, and you've got a state visit before you even start on other things.
"I think Beatrice and Eugenie are adding support where they can. They've always been clear they're non-royal, but they're always there to help fulfil any duties required."
Another source added: "Charles is very aware that his slimmed-down monarchy is getting positively skeletal. He is heavily reliant on Anne and the Edinburghs.
LATEST ROYAL NEWS:
"He is looking to bring in some fresh blood and he's looking to Beatrice and Eugenie. He thinks that they've grown into very sensible, lovely women who he thinks could be a real asset. Charles is listening to his public.
"They have been crying out for that royal glamour that has been missing during a time when his slimmed-down monarchy is in desperate need of bulking up.
"Beatrice in particular has been desperate for her chance to shine. She was once shy and her style was a little frumpy.
"But these days she's ambitious, confident and fashionable. She looks great in photos."
