Beautiful handbag. I usually only buy designer handbags of good quality. I am fond of a particular Tory Burch handbag that is no longer made. When I saw this handbag, which is similar in looks to the bag I can no longer find by Tory Burch, I decided to take a chance because it was on sale at an amazingly reasonable price. I am so glad I did. The bag is gorgeous, stitching impeccable, and leather excellent quality. Love all the interior pockets. Lining in side is beautiful. Also, not heavy even with all my stuff in it--do not hesitate to buy this bag. It is a very good find on Amazon.
