You might also want to check out the Dooney and Bourke online outlet called I Love Dooney. It's run by D&B, seems to have the same merchandise quality, and there are often better sales. I've shopped from I Love Dooney often and never had a problem. Their CS is by email, but they are much more responsive than the main Dooney site ( I have no idea why this is). You can return things to I Love Dooney, they have an online return form you generate, and for few things I have returned, I've never had a problem.
As for color, the denim is a mid blue, very pretty. In Florentine, it's very similar to the color they used to have called Ocean Blue. It's a little softer and lighter than a royal blue with a drop of green in the color mix. You wouldn't notice the green unless you compared a bunch of similar colors like ocean and denim. Then you can see that the denim is one drop more toward the green side. But Florentine handbags can vary quite a bit.... color, texture, even leather. Make sure you understand the return polcies where ever you order from.
