Length: 8.5 inches Width: 3 inches Height: 7.25 inches Strap: 42 inches It's a tale as old as time. Girl sees bag. Girl likes bag. Girl buys bag. But bag isn't used and just sits there. Why let such a lovely thing just hang around and not be used? The authenticity question: I don't know. There's no tag. This is a reposhed purchase from @lizzie924451, who reposhed from @janetedeleon. The photos with the yellow background are the latest. There are two think scratches on the back, which I honestly didn't notice until I took photos. It is a cute bag I wish I could justify keeping.
