Kate Middleton won't head to Wimbledon - with sister-in-law Meghan Markle in tow - until Saturday for the women's singles final, but her younger sister is already on her third visit of the summer.
The Duchess of Cambridge broke maternity leave, appearing at the Royal Air Force's (RAF) 100th anniversary celebration at Westminster Abbey on Tuesday. She has made three other appearances at family affairs since welcoming her son though-events the full royal family is expected to attend if they can.
The outlet reported that Kate felt the celebration was important to be at if she was feeling up to it.
Kate wore an icy blue Alexander McQueen coat dress and a matching hat from Sean Barrett.
Come Saturday, all eyes will be on her sister, Kate, who will join Meghan in cheering on Serena Williams.
Today, Meghan chose a long-sleeved, A-line black dress by Dior (it had a boat neck very similar to her wedding gown), a Stephen Jones hat and nude high heels, continuing her preference for neutral colours, simple silhouettes and French designers.
She teamed the look with Cartier diamond and white gold earrings, which are a favourite of hers.
She wore one to Princess Charlotte's christening in July 2015 and repeated the look for the Trooping of the Color in July 2016 and a commemoration ceremony in Belgium in 2017.
