I've been admiring PS1s from a far and think that I'm about to make the plunge to acquire one for myself, but I'm really unsure as to whether I should be in the market for a L or XL. It's going to be used as a work bag and I generally carry a moderate amount of stuff including: ipad, letter size files, make up bag (kate spade), gloves, camera, stethoscope, pager and id badge +/- 11" laptop and ipod charger. It doesn't sound like a lot, but fits comfortably inside my herve chapelier. What do you think? I'm only 5'4" so I'm worried I might be overwhelmed by the XL. Thanks in advance.
