Functional Beauty!
Color: Mystery Blosoom
I am so happily surprised as to how beautiful this bag is. The quality is fantastic and it is true to the description. I got the Mystery Blossom that looks like a Midnight Beauty to me. It has all the pockets it describes and the side ones are great with elastic holding your bottle or whatever you may use them for very securely. so it is very functional. I know you would be happy to have one or morey ourself. it is very lightweight so you can put alot in it like a laptop or tablet without it weighing you down. You can use it as a shoulder/crossboday bag or carry like a tote bag. I just love it.

Nice size, lots of pockets…doesn’t last.
Color: White Daisy in Black
At first, when I purchased it in May, the only thing I didn’t like was the useless middle zipper inside of the middle main pocket. But the rest of this purse bag is awesome!
Well… after 3.5 months, ALL of the inside stitching has come undone. Put something in what you think is the pocket, it’s not a pocket… it is between the lining somewhere. All of the zippers get stuck on the threads that are from the lining.
Cute fabric, but that’s all you’ll get… cute fabric.

Good quality, GREAT price, many features
Color: Vintage Sunflowers
I was searching for an inexpensive handbag (tote) like this in brand names. The prices were unforgiveable and just crazy! As I was searching on Amazon Prime, this handbag came up. It is really pretty and has ALL the features that I was looking for: Several pockets inside and out, very attractive design for Fall, AND a good price. My only concern/complaint would be that there are more zippers than I would have liked, slip pockets for glasses and phone are my preference. A long strap is included for shoulder wear; it is made of light weight material and washable.
