Hello Coach fans... Okay, so I have already been planning my next Coach purchase (though it may be a while away), and I've decided that I would like a more structured bag for my next Coach. I have decided to go w/ a Sig. Carry-all tote. But I have a few questions about them. First, how much larger is the Large than the meduim? Because when I recieved my medium carly, I was a little surprised, because I thought it would be a little bigger. So I want to make sure of the size. If you own one of these bags, a modeling pic and your height would be helpful if you have one. Thanks! Also, can you tell me what the difference between a lg. carry-all and a business carry-all is? I didn't see any differences between the pictures. Thank you for your help!
