The softest, prettiest pink ever. So finely constructed in every detail.
Size: One Size, Color: Crinkle Morning Beach
I recently ordered this Kate Spade Large Leather Shoulder Bag in the Crinkle Morning Beach color, which is a very soft, mellow, light pink. Think puffy clouds dusted with the pink highlights at sunset kind of light pink. I think it’s absolutely gorgeous!
I love the smooth, simple lines of this bag and the “rocking chair” curved bottom panel. The bottom panel allows this purse to stand upright, making it easy to see into it and access the contents. It has a simple thin shoulder strap tied into a perky loop detail at the side with a little tail. Nothing fussy. Just pure simplicity and class with a flirty little flair.
As mentioned in the description, this is a large bag, 14” wide, perfect for travel or if you have more to carry on that day. It’s quite roomy inside. The zipper opens up along the entire top of the bag, making it easy to see into it and take things in and out of it. There’s an open pocket against one side and a zippered pocket against the other to keep things neatly organized and easy to find.
The construction of this bag is perfect in every detail. The leather is just exquisite. So smooth to the touch. Even the light-colored inner lining is cool and smooth. Every surface has neat topstitching in perfect, small stitches in a matching pink thread color. It has a quality zipper that zips smoothly and has a small leather pull. It seems everything about this shoulder bag provides a delightful experience in its use.

A beautiful, soft, finely finished and costly bag
Size: One Size, Color: Crinkle Morning Beach, Size: One Size, Color: Crinkle Morning Beach
I defer to Mrs. Engineer in everything related to purses. I’ve included her comments below.
UNPACKING
The bag arrives surrounded by a thin foam pad inside a plastic bag. An unremarkable polyester storage bag (shown in a photo) is included. It comes folded in the same package as the bag.
IMPRESSIONS
The first impression the bag makes is that it's simple and beautiful and that the leather feels wonderful.
The interior has one open pouch and one with a zipper (see photos). That’s sufficient for Mrs. Engineer but some people may want more subdivisions of the interior.
The bag has top stitching everywhere. As shown in photos, there is impeccable top stitching throughout the interior and on the bottom.
The interior is light colored, a feature always desirable in a bag for ease of finding things.
The wide, flat (from front to back) bottom allows the bag to sit upright unless it’s loaded in an extremely unbalanced way. Because of the fineness of the leather, most people wouldn’t want to put it down on any flooring unless it was carpeted.
The handle is comfortable and is suitable for both handheld and over-the-shoulder carrying. The strap length can be adjusted to fit the user.
PRICE
It’s difficult to comment on the price and whether it’s a good value. Certainly all the functions of this bag, including looking elegant, can be accomplished with a bag costing a quarter as much. Whether the quality of the leather, the fineness of the finishing and the cachet of the Kate Spade brand is worth the cost of the bag depends on the eye, and the resources, of the beholder.
We received this bag at no cost through the Amazon Vine program in return for an unbiased review. For us, personally, it would not be worth its price at the time of this review, but the popularity of the brand proves that many others feel differently about it.
CONCLUSIONS
This is a beautiful and finely finished bag that we are happy to have, and there’s nothing negative to say about it. I’ve given it five stars.
