It looked huge to me... there's definitely a noticeable size difference. IMO it looks a bit big to be an every day bag, even to be a business briefcase as some other ladies suggested for its use. But if you like big bags it might work, it's just really...large. I think a bag that large would look better less structured, but because the design is so rigid it's almost like you're toting around a large drawing pad... or a serving tray... or a family size box of cereal (or two)...these are just comparison and I'm not trying to make it sound ridiculous at all! I didn't really play around with it or pay attention to it too much...but if it weren't for all those compartments I'd say the medium would fit inside the large. It's a really nice bag for sure, but way too big for me.
Can't help with the comparison since I don't have many Coach bags, but the large would be the biggest bag ever in my collection!
Thanks for the info!! I did lol at the cereal box comment! It sounds pretty big! I'm really hoping to see it IRL.
