Love darker polish shades, but don't want to go with a straight up black or brown? Try a moody forest green. Deeper than a bright emerald but brighter than a black-green, this shade lends a mysterious and, well, pretty badass vibe to any outfit you sport this fall.
A classic red will always be in style. The shade screams luxury -- think Louboutin crimson -- and flatters just about anyone. For fall, eschew typical blue-reds and opt for a deeper, more fall-like version of the color instead. It'll complement the muted colors of your fall wardrobe.
