Polka Dot Boston Bag

Soft totes usually slump in the middle by the time they reach the door, and everything inside has gathered at one end. A structured bag solves that and then holds about a third as much. This one keeps its barrel shape whether it is full or nearly empty, and the handles are cut short enough to stay on your shoulder instead of sliding down your arm. It zips across the top, so nothing gets out of it on a bus.
