Paris and Nicky Hilton enjoyed some sisterly bonding while shopping in Portofino, Italy. The heiresses soaked in the sun while going from shop to shop ... no doubt, dropping some major bucks.

We know they're sisters, but the two of them couldn't look more different. But we'll admit, we like their style.

Viva Italia!
