One of my favorite Rebecca Minkoff designs is her MAC clutch. I own six of these bags in different colors and materials and never get sick of it. The design tranitions flawlessly from day to night and is sizable enough to carry plenty of objects.
In fact, I carried my new copper snakeskin effect MAC today and it fit my continental wallet, keys, iPhone, lipstick, eyeglass cleaning cloth, inhaler, and lollipop. Actually, there was probably more in there, but it packed in nicely and was not bulky at all. This clutch is clutch.
