    Study and Attractive, but limited space.
    Size: Large, Color: 3-ostrich Purple
    I've owned it since Sept 2025 and used it about three times. The Pros are that it's a really rigid purse, like luggage. It doesn't collapse, which probably means it can handle a roughing up. (I'm not hard on my purses.) Another pro is that it's VERY attractive. I got the purple and it was quite elegant. The cons are that things don't fit into it smoothly. There's a zip pocket in the middle of the purse which is cumbersome. And though it fits a lot, there's a lot of work to configure it.

    Great Company and BEAUTIFUL purse
    Size: Large, Color: White Floral, Size: Large, Color: White Floral
    I wrote the following review. I changed from 2 starts to five stars. The company reached out to me and offered to rectify the problem. I am very IMPRESSED!!! I will say that a stranger thought it was a Dooney and Bourke!!! "I love this purse and have received many compliments on it. However, one of the pins holding the handles fell out somewhere. I tried to work with Amazon to get a new pin for it, but because I received it in March, they cannot do anything. I will use a paper clip to hold the handle, but obviously it will not look like a purse anyone would want to purchase. I expected it to last at least through the summer."
