Great bag!
Color: Black
I needed a black patent leather bag for an event and this was perfect! It is so pretty and classy! I actually changed the chain to something else that I had which made it a bit dressier, but overall this was a great purchase for the price. You can use it as a clutch but the chain was helpful to hang on the back of a chair. The only downside for me was the size, only because I wear glasses. I used a small "going out" wallet, had my car keys, phone, lipstick and glasses and that all fit, but it was tight. For a wedding or something when I won't have my car keys with me, it will be fine. Overall this was a great purchase, and arrive in a day!!

Lovely purse.
Color: Leopard, Color: Leopard
I was so pleased when I received this purse! It also has a Gold shoulder chain inside. I had previously ordered some shoes of this print. It was a perfect match! If you wear leopard prints, you understand. That was just lucky! AND I found a corsage! All from Amazon.
