This is a handbag that can also be worn as a crossbody bag. It has a wide gusset and a very smooth zipper. The approximate size is: Width: 28cm Height: 19cm Gusset: 12cm These are the external dimensions. Strip leather I received this from someone else, but I no longer have the opportunity to use it, so I'm offering it to someone who will. How about it for formal occasions, entrance/graduation ceremonies, or visiting family? Please understand that this is a used item that has been in someone else's hands, and only purchase if you are comfortable with this.
