The sisters spent some quality time together as they indulged in a spot of retail therapy at the Diane von Fürstenberg store in West Hollywood.
Paris proved she's a girl after our own hearts by rocking a high street dress from Topshop.
Her summery frock was adorned with a sweet daisy print, and featured black lace detailing and a flared skirt.
The best part? It has a bargain price tag of just £34 - hooray!
She accessorised her tanned legs with towering patent heels, adding a mock-croc clutch and her trademark oversized sunnies.
Nicky looked equally as chic in a paisley print minidress featuring a lace-up detail across the front.
The fashion designer opted for the comfort factor by donning flat sandals, shielding her peepers with tortoiseshell sunglasses.
After checking out the designer fashion gems, the twosome then headed to Mauro's Cafe at Fred Segal to grab a bite to eat.
But it seems their day didn't end there - this morning Paris tweeted: "Fun night hanging out at @KathyHilton's house with @NickyHilton eating chocolate chip cookies & watching Sex in The City. #SisterNight."
Can we join next time, please?
