Nicky - who gave birth to her newborn daughter on July 8 - was ever the doting mom as she pushed Lily in an UPPAbaby stroller.

She layered the stylish knee-length beige jacket over a casual buttoned-down denim shirt.

A pair of black leggings encased her long legs, highlighting the fashion designer and mogul's slender stems.

Nicky kept her piercing blue eyes concealed behind dark Ray-Ban shades and added a touch of sparkle with a gold necklace crafted with her daughter's name 'Lily Grace.' 

She accessorised her ensemble with a large black and white leather designer handbag and white Adidas sneakers with green logo.   

The younger sister of Paris Hilton, 35, received several touching Instagram photos and messages from the DJ spinning star.

Stay in the shade with these Ray-Ban's like Nicky

Nicky Hilton was spotted out enjoying the afternoon with her daughter in New York City. The heiress wore a chic camel coat and casual Adidas Stan Smith sneakers with her denim shirt and jeans. She finished off the look with chic Ray-Ban sunnies!

Ray-Ban is a celebrity go-to as we have seen on the likes of Gisele Bundchen, Beyonce, Lindsay Lohan and Charlize Theron.

This style is a classic and is not going anywhere any time soon so these are a wise investment for your accessories arsenal. They also flatter nearly any face shape so you know they will only compliment your look.

Pick yours up at Net-a-Porter for $160. If you fancy a few alternatives check our our edit below for similar styles. Ray-Ban also offers several color variations if you prefer brown or tortoiseshell.

We are so in love with the Topshop sunglasses and the Boohoo's are a steal at only $6!
