Nothing like a little vacation shopping!

The heiress dropped the dough on shades by Tom Ford and Dolce & Gabbana in Monaco, where she also got some goodies at FNAC and Sephora before heading back to the yacht (which is owned by Microsoft co-founder Paul Allen) and sailing to Monaco.

Paris and her sister have been all around Italy and the south of France this summer, with stops in Portofino, Monaco and now St. Tropez.

"Loving my summer with Nicky," Paris tweeted recently and we can only imagine why. A great yacht, fabulous locations and amazing company -- what could be better?
