A multi-functional makeup bag is essential for keeping your cosmetics well organized and protected inside your purse. A well-made cosmetic bag should be easy to clean and keep your items from breaking inside your bag.

Even among daily and travel makeup bags, there's some variation in size. The best option depends on your routine. For example, if you only want to bring along some powder, lip balm, and lipstick with you for touch-ups throughout the day, you don't need much space. However, if you also want to bring along eyeshadow, liner, and mascara to turn your daytime makeup into an evening look, you'll need a larger bag.

A daily makeup bag typically doesn't have to be all that durable, so a soft-sided style works well. For a travel bag, though, it's a good idea to choose a bag with a hard exterior. This can keep containers from breaking inside it if they get jostled around on a plane or in a car or train.

Consider a waterproof bag. There's always a chance that the bottles and containers inside your bag may break. To keep any liquids from damaging the bag or leaking out, choose a waterproof bag made from nylon, vinyl, polyester, or another waterproof fabric. Look for a bag with dividers to separate your products.

Whether from powder, cream, or liquid products, some mess is inevitable with makeup items. Make sure that you choose a bag that has a liner that you can easily wipe clean with soap and water. Look for one with a vinyl lining -- they're usually the easiest to clean.
