It’s Okay!
Size: One Size, Color: Soft Mahogany
Everything was just okay about this bag. I expected more of a high quality and gorgeous suede and it really looked like I could have gotten it at target. It did not lay quite right as a crossbody for me so I returned it. The color is very pretty and it is made very well.
