Beautiful and very very spacious
Size: One Size, Color: Seaweed, Size: One Size, Color: Seaweed
So spacious!! This could almost be an east-west style work bag if you are someone who uses an iPad rather than a laptop. A standard 11 inch iPad would fit in here no problem along with your basic essentials like your wallet and phone.
Its could be too big as a daily bag for some, unless you carry a lot. But I like it as a daily option becuase I can fit a waterbottle and maybe a snack along with my essentials if I need to!
It doesnt look too big though when worn, since it is a slouchier design and the leather is softer, it creates a cute crescent shape when worn. This makes it look slightly more compact since it folds in on itself a bit creating that cute slouchy shape.
The leather is decent quality. I have 3 other kate spade bags and 7 coach bags, and this pebbled leather is actually a finer grain than the other kate spade bags I have (1 deco shoulder bag and 2 medium dumpling satchels). The pebbles in the leather are slightly smaller, i think this is so it has a more relaxed texture. I like the leather on this bag more than my other kate spade bags. It almost feels comparable to coach pebbled leather on the legacy bags. (even though they are under the same parent company, coach leather quality is often a bit better than kate spade.)
I would highly reccomend this bag if you like the coach Brooklyn shoulder bag 28 or 34. This is a similar simple hobo/slouchy style that hangs close to the body and armpit, but is much more spacious and the pebbled leather will be much more durable than the fine grain leather on the brooklyn, which i have found scratches super easily. Plus, this has a zipper and 2 storage pockets internally for organization!!
I would say this is worth the price if you get it on sale. Kate Spade often has great sales compared to coach bags, which rarely go on sale, and if they do, sell out super fast.
Kate Spade bags last forever and I feel deserve just as much hype as coach bags for their fun styles and decent leather quality.

Slouch Master!
Size: One Size, Color: Black, Size: One Size, Color: Black
The size of the bag, the two pockets big enough to fit my phone, and the silver hardware are what sold me. But oh, the slouch is top tier.
It's fitting my large coach wallet, nolita 19, and a small baggu pouch with plenty of extra room.
It came factory wrapped and shipped overnight.
I added carabiners to attach my chains, but if Kate Spade added small charm rings at each end it would be even better.
