1. Premeditation and Treachery
I know going window shopping is so fun. But sales are not. Sales are serious. You should go shopping with a clear idea of what are you looking for. Open your closet and see which items could complement the clothes you already have. Take into account colors, matches, materials and shapes. Make a list of your needs and stick to it. This way your buyings will be valuable and useful, and won't end as your last year's pailette skirt which you gave to your niece. Having this kind of organization will help you to buy better, faster and wiser at the sales.
