Kate Middleton Goes Sporty Chic At The America's Cup World Series

The Duchess of Cambridge attended The America's Cup World Series on Sunday looking as lovely as ever.

Kate Middleton sure does sporty chic well!

On Sunday, the Duchess of Cambridge attended The America's Cup World Series event in Portsmouth, England, marking her first public appearance since the birth of Princess Charlotte.

For the occasion, Catherine wore her trusty Breton stripe shirt with a customized stretch fleece Ben Ainslie Racing collection sweater by Henri Lloyd on top, which had "The Duchess Of Cambridge" stamped on the back. Dark blue skinny jeans from Zara and flat slip-on moccasins from Sebago finished off the ensemble.

In keeping with the sporty theme, Kate pulled her brunette locks into a mid-height ponytail, with strands of hair wrapped around the elastic for a more polished look. Her makeup look was simple, consisting of a bit of eyeshadow, pink lips and a hint of blush.

Also in attendance was Prince William, who wore a matching BAR top with "The Duke Of Cambridge" written on the back.

And it looks like Prince George and Princess Charlotte will be dressing like mom and dad very soon, as Kate was gifted two mini versions for the tiny tots.

Here's hoping we'll see some pics of them all together soon!
