A black maxi dress is formal holiday dressing that works everywhere from cocktail parties to black tie events. Black reads as elegant and does not compete with jewelry or accessories. The full length is what makes it feel special. The silhouette matters so look for something that is either fitted through the torso or has interesting draping. The fabric should be substantial enough to hang well. A black maxi works because it is timeless and versatile. Pair it with jewelry and shoes that match the formality of the event. These dresses work for people who want to feel sophisticated and know that black does exactly that.
