What a nice surprise
Color: Black, Color: Black
This purse totally surprised me. It is so nice. It feels rich, soft but structured. Looks way more expensive. I love it. Update. My only complaint after using is the magnet closure isn’t really strong so can open easily

Amazing bag
Color: Black
Omg this is seriously the cutest bag. I purchased the black so classy looking and I love that you can carry It 3 different way. It looks like an expensive bag. Can’t wait to use It at some weddings as a clutch and then a cross body or shoulder bag other days. . It has card slots in It which is so good when you don’t want to carry a wallet. I did put a small wallet my phone and lip gloss and keys and still have room.

Nice bag
Not a bad bag just not my favorite. Looks different once it came in the mail and the quality wasn’t as nice but still very spacious. It’s a nice daily bag but not what I had needed.
