Unlike the outfit you might wear to your friend's holiday party, the dress code at your family soiree is probably a bit more conservative. While you want to look fun and festive, it might not be the place to break out your sexiest tops or trendiest dresses. Look for classic dresses with a little sheen or embellishment and an ultraflattering cut. Add a touch of color with a pretty necklace or a pair of jeweled earrings and finish with sweet heels (and tights, if necessary!). The result? An outfit you and mom can agree on.
