Wear dark colors, like eggplant. They help hide the stains that naturally occur when you spend your days mauling elk and rubbing against trees.

As a bear, you are probably well aware of the unflattering side effects of preparing for winter. To help you maintain some of your ladylike curves while you are out in the hills stuffing your fat face with berries and snails, you should wear cinched-waist dresses and shirts.
