This is my authentic MCM sling bag that I used for one very short trip to FL thinking it would get tons of use after. I was mistaken. It is quite the convertible bag! It can be a sling bag, a belt bag, a crossbody bag, a bum bag. It comes with the strap. Approximate Measurements: 9”L 5”H 2.5”D All of my items are from a pet friendly, smoke free home. If you have any questions, please reach out before purchasing.
