They all look authentic. The second one isn't style 9790. Seller didn't give any measurements but it looks like a compartment bag.
Whateve, Thanks for pointing out the wrong style. I get so confused with all these crossbody bags that look so similar to me. I was able to get dimensions from the seller - 9 inches wide, 6 inches tall and 2 inches depth.Hopefully that provides more clues. Thanks.
