Shape definitions

  1. I'm a newbie. Please excuse my ignorance, but I can't seem to find a definition for "east/west" bag. After looking at various pictures, I assume that it could mean that the bag is considerably wider than it is tall, but I'm not sure. I also sometimes can't tell the difference between a shoulder bag and a satchel, or even certain bags classified as hobos. Is there some sort of standard reference I can consult to educate myself? TIA
  2. This glossary/picture reference is very helpful. Thank you, Passerby!
