this bag is awesome. i didn’t realize how similar it looked to the brooklyn coach bags! it’s good quality and holds a LOT. also super cute. the material is nice and you can wear it anywhere, dressed down or up. it’s nice and smooth! and the zipper feels pretty secure. i’ve had this bag for a couple months now and it’s still holding up great 🤍 i’ll have to buy more colors i can fit a full size round hair brush, a bag of all my makeup, my wallet, 3 pairs of keys, a full size stick deodorant, a full size spray deodorant, tons of lip products, gum, oil blotting papers… i mean it’s roomy. and i bring basically everything with me at all times, so if i approve then im sure you guys will too, lol

Very Nice Purse

Color: Black

I love the look, soft leather and good quality. Although the size indicates small, I would say it is medium size.

Good value

I really like this bag. It looks more expensive than it is. I get a lot of compliments. Roomie and lightweight. Just the right size for my purposes.
