So spacious, great school bag
Color: Black, Size: One Size
I love this bag! I was looking for a bag that would hold my laptop without looking like a school bag, and this is perfect for the job. It fits my MacBook, granted it’s a tight fit with the case on, and it’s like a bottomless pit. I lose things in there so often, it’s so big. I’ve been using it for months now and it’s showing pretty much no signs of wear, and it’s pretty lightweight until I put my school things in it.
It has two pockets on the interior, one open one on the side and one that zips up on the other side. The one that zips holds a decent bit. I held a ton of makeup in it before I decided I needed something better and that I was making it poke out too much. I don’t use the other side as much. I hold a couple of things in it, but nothing that can easily slip out.
Ultimately, this bag is sleek and easy to carry around, it’s also not uncomfortable to wear when holding heavy things. I feel like skinny straps always dig into my arm, but this one is comfy. I liked it so much that I got another one in red as well. Overall, it’s a great bag and I recommend it to anyone who needs a Mary Poppins bag to hold a lot of things.

spacious, pretty and super sturdy!!
Color: Burgundy, Size: Large
soooo nice I’m obsessed! I treat my purses like black holes but I wanted something I could customize to my liking and it’s big enough I added a bunch of small bags inside to separate things and it’s still so spacious, and the wine color is my fave this season

Love it
Color: Cream, Size: Large
I love this purse, not too big and not too small. I love the soft leather and also because I can use it when I dress up and or dress down, looks good either way. And the makeup purse is a great addition to help keep all my things together. Love it

Good bag! Lots of space inside and very cute.
Color: Green, Size: One Size
My everyday purse! Really comfortable to wear and fits lots of stuff. I can fit my macbook air, a toiletry bag and a small makeup bag! Although it did come with some thread strands when i first got it, i just cut them and haven’t had an issue since.

Fabulous Bag
Color: Black, Size: One Size
When I picked this bag I was so unsure of what I would receive. This is a fabulous bag with so much room, easy to carry, lightweight, and such a great bargain for the price. It has a good zipper and I love using it over my more expensive bulky heavier bag. The balck is elegant and perfect for day or evening time.
