Gotta Love Kate Spade
Size: One Size, Color: Southwest Desert
This Kate Spade purse is a great size leather purse. It fits all the essential items. It is very fashionable for casual, and business casual. As with all Kate Spade purses, the quality is wonderful, bag is fully lines, with some small pockets inside. I also loved all the color choices, but I went with the Southwest Desert, and I do not regret my choice at all! The price point for this purse is in line with other designer purses this size.
