I bought this in black leather. It's the Madewell crescent bag and it's just perfect. Great size, beautiful feel, and so roomy.

Gorgeous bag!!!
Size: One Size, Color: Aged Cognac
Don’t hesitate to buy this bag! It’s beautiful, soft and roomy without being huge. Color is also beautiful and the studs on the side give it a special look!
