Sonia Kashuk Completely Organized IT Bag, $15,

This, people, is evolution in action. A black-nylon makeup bag is and has always been the best makeup bag because it lasts forever, is lighter than air, can be washed if dirty and generally never reflects its age or treatment in any way. This black-nylon makeup bag is full of pockets, so it’s instantly 1,000 times more useful. The chic wine-colored zipper tabs make it ... chicer. And unlike its earlier, less pocketed brethren, it costs only $15. Amortized over forever, you pretty much make money buying this bag.
