Great value for crossbody purse.
Perfect size, made well, zippers are heavy duty, really love this cross body. Was hoping in could have gotten gold hardware on the black bag.

excellent quality

Quality leather and construction! I wish the strap were a tiny bit narrower, but I cannot complain about such a well-made bag!

Nice strong leather, good purse
I generally liked this purse but ultimately returned it because I could not wear over the shoulder. It's good as a clutch or cross body. I tried as a cross body but it would slide to the front when I walked, maybe that's just a cross body thing in general, I don't know.

It's elegant in a simple, understated way. I love it!
Looks like expensive, pebbled leather. just enough pockets to fit all my things. slim design, but roomy enough fit many items. I like that the hardware is silver. It looks sharp with the black purse . love the two straps, so it can be worn on the shoulder or as a cross body bag to keep hands free It's elegant in a simple, understated way. I love it!

Oversized Logo ruins the look.
It's a great bag, lots of space, pockets and super cute except for the GIANT LOGO embroidered on one side. In the pics you think "maybe it won't be that bad in person." Well, it's worse in person. If this were a Gucci, Coach, MK - it would be great. But this is some random no name - and it's an ugly patch.
