Lucky Brand at Amazon Prices
Size: One Size, Color: Rose Quartz
Who doesnt love the smell of a new leather purse? And from Lucky Brand at Amazon prices? Sign me up! I plan to use this as a crossbody as the strap is the perfect length. So cute, great size and smells fantastic.

Super cute… but not what the listing is
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
First of all, this listing is entirely inaccurate, as other reviews say, the picture is of a larger bag when in reality you are sent something much smaller and without the small wallet. I wanted the smaller bag, so I ordered it intentionally, but if you are looking for the larger size, do not order this. I included a side by side comparison of the two bags. The lighter bag is the size this listing is supposed to be (that I owned previously) and the smaller one is the one I was sent. That being said the smaller bag is super cute and so similar to the Brooklyn bag! Just be aware that it does not match the listing :)

Material
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
This purse has a good size for an every day purse. It’s a pretty style purse, and reminds me of the Coach brooklyn shoulder bag. I’m not too crazy about this bag since the material is thin and flimsy, but I should be okay.
