I'd go for the Coach. I love that they used leather and suede, and the gunmetal hardware looks gorgeous against this shade of green. Also, the bag is rectangular, so I assume it would fit more stuff than the Polene.
The combo of materials in the Coach is definitely one of the things I like about it. I’m also heavily swayed by the fact that it will hold more… I have plenty of small bags and the Tabby reminds me of the Marlie, which is a Coach outlet bag that I’ve found to be crazy functional.
