LOVE IT! But let's clarify the color!
Color: Apricot, Size: 14 Inch
Hi! I bought the 14" backpack in apricot. A few things stand out to me: 1) High Quality-this is a quality-made product. 2) The Apricot color is closer to a light tan or light sand color. 3) It was not as wrinkled upon arrival as I read elsewhere. I do not intend to steam the wrinkles out. I don't see that as necessary and I hate wrinkles. It's beautiful! It's high-quality. It has every pocket and function you'd want. (see the videos.) Once I use it more, I'll add to my review if necessary. I love it. I'm happy a bought it and I think you would be too! Nice to get a product with such obvious quality!

Cute and company, but packing makes it VERY wrinkled
Color: Black, Size: 16 Inch
The bag is really cute and designed so well, can't believe how spacious it is yet compact! Not bulky and doesn't take up much room, lots of pockets. Perfect for both fashion and function. Took off stars thought because it came folded in half in its package and it's VERY wrinkled. Kind of takes away from it's look and makes it look bad :( pretty major wrinkles everywhere and I'm not sure if it can come out in this material, though I will try ironing it. If the company shipped it better it would be 5 stars.

Great stylish work backpack
Color: Black, Size: 16 Inch
I’ve had this backpack for a year and a half now and it has held up very well. I use it for work and work trips. It has many pockets for organization and fits everything I need including my 14 inch work laptop. Very stylish (not sporty) and appropriate for the office.
