Lots of storage but compact look
Color: Mocha Brown
I was looking for something for my corporate 9-5 and was over a tote bag. This is perfect! It fits so much without it feeling or looking bulky. Love the amount of storage it has and I think it would even be a good travel bag

Defective
Super cute bag, unfortunately it was less than functional.
The main zipper cannot zip up completely, as it has been sewn incorrectly.

I got this bag as a gift from July and started using it in the middle of September for work. I love it but the left strap is pulling off. I am very disappointed.
