I chose a Kelly longue over the Medor because I thought it would be easier to hold. As much as I think the Medor is a fantastic looking bag, it just didn't look like I could deal with the hardware poking into my hand. I also liked my Longue because it was swift and wouldn't show the finger nail scratches that the box leather would show.
Based on your dresses, which were all really super!, I would order a black croc Kelly longue or smaller clutch.
