This backpack / purse is the perfect size.  It holds everything I could possibly need and then some.  Ordering on line I always worry that it won't be the size I expect, but this one is perfect.  I can fit, wallet, makeup bag, sun glasses, phone, water bottle, small umbrella, and more.  I don't usually carry that much stuff, but when I do, it will all fit perfectly.  I recommend this bag.  Very sturdy.
