I love this bag. I bought it for essentials like wallet, sunglasses, phone and it fits everything nicely, maintaining its structured shape. The lining is gorgeous as is the outside. I like the adjustable strap as well with the chain embellishments. It is lightweight and it's clear that it will last. So far I've never been disappointed in MK products.
