I have a saffiano tote that's held up well. I love that it's lightweight, can be used in any kind of weather, and doesn't get scratched or show wear easily.
To get an idea of what the wear on certain bags is like, a good place to check is eBay. You can do a search for "Michael Kors saffiano" and then on the very left, you can check where it says Condition > Used. You can also scroll down and check Show only > Sold listings to see more used bags that have been sold. I also like to check out how a bag wears before actually purchasing it, and have found eBay very useful. It's saved me from purchasing bags that I wouldn't have gotten much use out of. Hope that helps!
