Practical and pretty
Color: Silver
This is a three pocket purse. One top zipper covers all pockets. It is the only evening bag I own that has enough room for all my stuff. At my age I need more than a comb and a credit card and keys. The crossbody chain is pretty and does not look cheap. I wear purses this way so that my hands are free to do what I want, like dance, go through a buffet line, stand and talk, etc. Even though this is not a costly bag, it does not look cheap. I would recommend this without reservation.
