RueLaLa will have Lilly Pulitzer on sale tomorrow (11/17)starting at 11am eastern time. Lilly is one of my favorite brands but I really only buy it when it is on sale : )
RueLaLa is a discount website that features "flash sales" on brand name clothes, shoes, beauty, home decor and more. Their sales feature a limited selection of deeply discounted items. Popular or majorly on sale items tend to go fast so I would log in right at 11am if you can to get the best deals.
