Best gift I gave my wife in a long time!
Size: One Size, Color: Parchment Multi, Size: One Size, Color: Parchment Multi
As someone who has never purchased a purse before, I wanted to get my wife something special for her birthday. I know she loves Kate Spade products for their excellent quality, so I decided to go with one of their purses. I’ll admit, I was a bit shocked at the price initially, but given its designer status and popularity, I should have expected it. When the purse arrived, I immediately understood why it’s priced the way it is. The craftsmanship, from the stitching to the overall quality, truly stands out. The difference between this and a purse from a big-box store is remarkable. Needless to say, my wife absolutely loved it. For a purse to impress both her and me, it’s an easy five-star rating!

High quality clutch with beautiful details.
Size: One Size, Color: Parchment Multi, Size: One Size, Color: Parchment Multi
Quite obviously you are paying for the name with this - as a middle-class mama wouldn't normally pay $200 for a clutch. BUT, if you love and can afford Kate Spade, this doesn't disappoint. It's obviously high quality, and the tri-tone is beautifully neutral (will go with almost anything). I thought it would be bigger because I didn't do my research; 'pochette' is French for an envelope shaped handbag, and this is definitely that. More of a small clutch - that will fit your cellphone, sunglasses and a couple other essentials. I do love the slim wallet attached by a chain that sits in the front pocket, so you can access that without having to dig thru the purse. Beautiful gold details, and high-quality zipper. Definite splurge - just need to find some pumps to go with it now for the wedding I'm taking it to!

Small size, minimal space
Size: One Size, Color: Parchment Multi
I am a huge Kate Spade fan and so happy to add this to my collection! It is more than reasonably priced for the quality and big designer name. It is small, and very minimal, just right for those times when you want to carry only the basics. The neutral tones are gorgeous and all the materials including leather and hardware are premium quality. It comes with a storage dust bag with the Kate Spade name and every bit of this pochette comes individually padded and wrapped for shipping. There is so.much.wrapping! To me it's overkill and wasteful, but they really ensure ultimate protection in the shipping process.

Loveeee
Size: One Size, Color: Parchment Multi
This bag is SO cute. I don’t normally wear bags like this, but I’m obsessed. It’s definitely small.. but perfect to wear on a night out to hold the essentials. You can tell it’s a good quality purse right away just by looking at it.
