Too small inside
Color: B4/Chalk
The purse is nice but nothing fits inside. I returned it. It comes with a little slide in wallet. I took that out and still could only fit my iPhone. I could barely squeeze my key fob in with the phone. It had trouble snapping closed with both those things in it

One of a Kind — Made Really Well
Color: B4/Denim Multi
Leave it to Coach to create this adorable bag. It has embroidered cherries and small leather leaves. The packing for delivery was unbelievable. All the hardware and leather was protected by small pieces of foam. My only disappointment is that there is no zipper pocket on the inside. It is small so if you carry a lot, this won’t work for you. It will be a nice spring/summer bag.

Instant-On Sight-Love Affair
Color: B4/Indigo, Color: B4/Indigo
The bag is adorable! I loved it instantly before even completely unwrapping it. It feels very well made. It's compact but spacious. I'm surprised it doesn't have an inner zipper pocket but it makes up for that by having a zipper that closes the whole bag rather than a snap. And it has 2 outside pockets with closures. It smells like a brand new pair of jeans. I can’t wait to accessorize it and upcycle it to my style. Also, I appreciate learning that it is made with sustainable materials. What a bag! I bought this as a replacement for my Brandon Blackwood waxed denim ESR tote that’s seen better days. They are about the same size but the Coach bag is a bit more spacious. They’re both the same price and seeing as the ESR is 5 years old, I’m surprised the Coach doesn’t cost more. Definitely worth the price. Didn’t want to risk it being sold out to wait for a sale.
