Understated, yet very app
Color: Apricot, Size: 16 Inch
I find this backpack to be sleek and modern,. I do not like to carry bags that take attention away from me and onto my things. It is sleek and femine - I love the backpack and I’m glad I bought it…

Cute, functional bag that’s very stylish
Color: A-pinkish Grey, Size: 14 Inch
This little bag is so cute and fictional. It’s the perfect size and the color is gorgeous. Matches my style really well. It also is a smaller size that fits many things which is really hard to find. It’s always usually a bigger bag so I absolutely love this one and highly recommend it.

Its ok
Color: Black, Size: 16 Inch
I ended up returning it as it wasn't quite what I needed. I actually thought the bag abd design were ok. Its not worth the price is paid either.
