The Duchess of Cambridge, 40, was in high spirits as she arrived at the tournament alongside her husband the Duke, and their seven-year-old daughter, where they took their seats in Sandwell Aquatics Centre to watch the swimming heats.
The mother-of-three appeared trendy in her £1,945 white Alexander McQueen trouser suit for the event, which she first wore during the Caribbean tour earlier this year.
Meanwhile Princess Charlotte, who was wearing a £44 Rachel Riley dress, appeared delighted to be attended the contest, gesturing wildly to her parents as they sat in the stands.
In a cheeky display, the seven-year-old could be seen clapping along enthusiastically, sticking out her tongue and gasping at moments of action – while her mother tenderly tucked locks of her behind her ear which had fallen from her neat plaits.
The little royal is proving to be quite the sporting fan – days ago, she joined her father for a video message in sending her best wishes to the Lionesses ahead of the Euro 2022 final.

The royal swept her long brunette locks back from her face in a bouncy blow dry for the occasion.
Meanwhile she kept her makeup neutral for the occasion, opting for a sweep of dark eyeliner and a touch of lipstick.

Senior royals are representing the Queen at the Commonwealth Games as she continues to take a step back from royal duties. The monarch, 96, remains in residence in her Scottish home of Balmoral, in Aberdeenshire.
Prince Charles stood in for his mother at the spectacular opening ceremony and was greeted by cheers as he drove into the stadium in an Aston Martin.
Meanwhile Sophie and Edward have made a number of appearances during the competition thus far.
The couple attended the contest yesterday alongside their children Lady Louise, 18, and James, 14.
James and Lady Louise joined the rest of the family for the Queen‘s Jubilee celebrations earlier this year, but have largely grown up away from the limelight.

Last week, the Countess of Wessex re-wore a favourite blue patterned dress as she joined Prince Edward at the Commonwealth Games on Friday.
Sophie donned a £795 frock from royal-approved designer Peter Pilotto to take in the action across a number of sporting events.
The couple started off with a trip to the gymnastics arena before taking their seats for a rugby sevens match.
Prince Edward put on a particularly animated display, holding his head in his hands as he struggled to watch.
