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.

My bag strap pulling out.

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.
