We don’t call it a “murse” here, it is a straight up BAG. Something slightly smaller than a messenger bag (no one is on a survival mission, we all have cars here), yet big enough to carry scripts, a laptop, headshots, etc. Maybe a little stash pocket for your “medicinal marijuana” that you need between those long meetings with directors. Top picks are found at cool stores like Union, Opening Ceremony, and Barneys.
