This bag is made from that polyester suit/skirt like fabric, it's a fantastic grey with a sophisticated turquoise, brown and black plaid. The inside is lined with a turquoise broad cloth. There are two buttons, one is an accent and also used to close the bag, by looking the elastic attached to the opposite side on the inside of the bag around it. You can see this in the top and bottom right pictures. The picture on top, shows the elastic attached with a button, this is to make sure it's strong and won't pull off. If you don't want to close the bag, you can use this loop to attach your keys to.
The handle measures just under 21 inches, perfect for your shoulder. The opening is 10 inches wide, from the opening down the bag is just under 11 inches deep. The bottom width of the bag is approx 11.5 inches (the corners are rounded so that's about the widest part of the bag).
