This purse has a good size for an every day purse. It’s a pretty style purse, and reminds me of the Coach brooklyn shoulder bag. I’m not too crazy about this bag since the material is thin and flimsy, but I should be okay.

Not the same bag

The item I received appears to be a smaller version of the bag without the small wallet that should be included. Do not buy it, and save yourself the trouble of having to return it.
