No value for the money size is ridiculous. Loved the color us
Size: One Size, Color: Purple Agate Suede
Over the years I have bought a few Kate Spade bags for my best friend who loves them. Nice bags for maybe $50-$100 more than I paid for this. This looks like something you mail your electricity bill in. No value for your money. I loved the color but the size was ridiculous, comical even.
