Pregnant Pippa Middleton nails Wimbledon-chic in white dress

While speculation is swirling over whether or not Kate Middleton will interrupt her maternity leave to make an appearance at Wimbledon, her two younger siblings are already making the scene at Britain’s famous tennis competition.

Pippa Middleton wore her best Wimbledon whites and what appeared to be a new layered lob haircut as she joined brother James, who is the youngest of the three Middleton siblings, for some Grand Slam action Thursday. The Duchess of Cambridge’s younger sister wore a white broderie anglaise dress designed by Anna Mason London, which she paired with rounded brown sunglasses, blue wedge espadrilles, a Jess Collett straw hat, and a cream clutch.

Though Middleton is known for favoring reasonably priced designs from retailers like J.Crew, her Wimbledon wardrobe was a bit of a splurge. The Bergman dress is priced at £680, or about $900 U.S., and also comes in black.

It’s the second Grand Slam tournament Middleton — who is expecting her first child with husband James Matthews — has attended this summer. She and Matthews were spotted at the French Open in May, just days after they attended the royal wedding.

Speaking of which, Middleton’s famous big sis isn’t the only royal who may be making a trip to Wimbledon. Royal-watchers are also keeping their eyes peeled for Meghan Markle, who may be on hand to cheer on pal Serena Williams.
