Cozy In a Maxi

I've been wearing my maxi dress in warmer weather, but wanted to see if I could transition the piece into something more suitable for the cold. I stuck to a growing favorite color combination of mine, navy and red, added a chunky scarf, then... got stuck on what shoes to wear. Black flats? Flip flops? Nude flats? Flat boots? I figured most of my foot would be hidden underneath the hem, so nude flats would blend in better with surroundings. Nope, of course the way I was standing made them the most visible. I think I should've went with plain old black flats. What are your thoughts on shoe pairings with maxis? sunglasses: Old Navy (similar)scarf: gift from SewPetiteGal...
