Yves Saint Laurent colors shopping hand in hand Yves Saint Laurent colors shopping hand in hand paris Hilton Nicky Hilton

Spring has sprung, so of course it's time to go shopping for new rags!

After grabbing lunch at Lemonade with Doug, Paris and Nicky dropped some dough in Beverly Hills yesterday afternoon. Of course the sisters wore typical Hilton-esque outfits - Paris rocked a colorful dress, while Nicky sported a more neutral getup.

While the girls were inside doing some serious shopping, photogs asked Doug if he had proposed to Paris, to which he replied, "Not yet." What's THAT mean?!
