Product Description:This is a curvy and fun hipster cross body bag made out of a really cool science themed cotton print. The bag is fully lined with a cotton print of handwriting and I used a math themed fabric for a wonderful accent on the closing flap on the exterior. This simple purse is a great way to show off your interest in life long learning. Exterior measurements are approx. 12" wide at the widest part. This bag is curvy so the bottom is only about 9 1/2" wide and the top is only 9" wide. There is no depth measurement as this bag does not have a gusset or flat bottom. It is about 9" tall. Strap is not adjustable but has a 21" drop to the top of the bag. Many people may find this comfortable enough to wear crossbody style.
