Too many working moms make the mistake of dragging the big Kid Bag to the office. This isn't very professional looking (the Kid Bag, after all, is the one with the peanut butter smeared on the outside and the collection of My Pretty Ponies on the inside), but beyond that, it makes it hard to switch gears and stop being the mom while you're at work (every time you reach inside for a file, there's a pony!). Instead of lugging the same bag everywhere, get yourself a great work bag, one that is just big enough for what you need for the office. No kid stuff allowed.

This CL by Laundry bag is perfect for work: big enough for everything you need for the office, but sleek enough to tuck under your arm -- and certainly NOT large enough for a sippy cup. The hobo styling and buckle detail give it a clean, professional look, and the shiny patent fabric makes it both easy to clean (wipe with a damp cloth) and a little bit dressy.

CL by Laundry buckle patent hobo, $38.00 at J. C. Penney. Also available in red and mustard.
