Engagement looks good on Pippa Middleton! Days after Kate Middleton's younger sister announced her engagement to financier James Matthews, the fit star ventured outside her home in London in a printed dress with a keyhole cutout that perfectly displayed her toned figure.

Middleton flashed a smile to photographers as she left her Chelsea home on Thursday and looked as polished as ever as she made her way through London's streets. The star wore a knee-length patterned dress with a ruffle at the hem and accessorized with a matching navy satchel and strappy block heel sandals. While we love her classic look, we can't peel our eyes off of her dazzling diamond.

The newly engaged star flashed her stunning Art Deco-inspired Asscher cut ring, which reportedly cost upwards of $260,000, on her left hand. The outing comes just one day after she donned a tank top and athletic shorts to take a jog around London--for which she naturally had her new sparkler in tow.
