boots shoping heiress Paris Hilton Nicky Hilton sunglasses

No one knows how to shop like the Hilton sisters!

Paris and Nicky took a stroll together in Beverly Hills ... going in and out of stores and walking out with plenty of pricey purchases.

We're loving Paris' Chanel purse! Nicky was sporting Christian Louboutin wedges and an Ella Moss dress. Fierce!
