I love my Potiron Togo but if I would've had a choice, it would have been Chevre, hands-down, because it's my favorite Hermes skin.
Potiron Chevre is gorgeous and a little deeper in color than on Togo.
Potiron chevre sounds perfect - but I'm pretty sure I wouldn't turn away potiron togo, either! Potiron is one of my very fave colors. GL in your quest for a potiron Birkin.
