Not the same bag
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
The item I received appears to be a smaller version of the bag without the small wallet that should be included. Do not buy it, and save yourself the trouble of having to return it.

Size: Medium, Color: Dark Cappuccino
The dark cappuccino brown is pretty. This is a favorite just because of the color of the tote. The inside lining color makes it easy to find items. I like it so much I ordered the black one.

Love the style but it doesn’t hold shape
Size: One Size, Color: Vanilla
I am big fan of the Lucky Brand. This tote disappointed simply because it was floppy. So if you set it down it just collapses instead of holding shape. So it wasn’t what I was looking for in a tote. I was really excited about this bag because I love the style and color. But I ended up returning it.
