Color is off
Color: Bronze
I love the purse. The material is soft and the purse holds a lot. However the color wasn't close to what I ordered. Luckily I had a dress to match.

Beautiful and sleek black hobo bag!
Color: Black, Size: One Size, Color: Black, Size: One Size
This purse is absolutely lovely for the price! Such a cute hobo bag, yet is modern and sleek to make any outfit look polished. It is super soft and has a faux leather texture with a beautiful sheen to it. It seems like great quality and if it ever gets saggy or old, it's cheap enough to replace easily. I love the gold hardware and it also has a lovely gold metal label of the brand on the outside making it look expensive. Also the strap is thick enough that it is quite comfortable on the shoulder. The only gripe I have is that it looked a bit bigger online, it fits about as much as a tote bag would; also the pockets inside are a bit small, but overall, I LOVE it!

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
