Open-toe Shoes in the Winter?!

Suite 7 is just around the corner, and I am so excited for all the fabulousness that will take place. However, I have a very important questions for my readers. Is it okay to wear open-toe shoes in the winter?

The outfit I have in mind would look so much better with a simple open-toe strappy heel (ie. Stuart Weitzman's The Nudist), but I'm not sure if it's acceptable to wear the shoe in mid November. I mean, I've done it before, but on a casual girls night out - not to a fashion show. Whats your take? Are open-toe shoes in the winter (cold months) a no no?
