Good size and stylish. Wish it could be made shorter
Size: One Size, Color: Black
This is a great purse and very stylish. Great size. Only think I wish is that I could have adjusted it to be much shorter of a hang. I am quite small so the size is great but I am going to poke a hole in it to make it shorter and then modify the end. It will then be perfect for a night out when I don’t need much to carry.
