I think the best part of this outfit is the colorful J.Crew wool scarf. It's older but the colors are classic so it's easy to find similar scarves at a number of retailers right now.
Boot is not on my sweater, it's hovering. :) Takes a steady hand.
I usually wear this scarf from late November until the end of January because it gives a festive vibe to outfits. This time I tied the ends together like an infinity scarf.
