Taupe evening dresses are quite rare, and look sort of old-fashioned.

Girls going to retro-themed proms could look perfect in an Elie Saab evening gown like this one Christina Applegate wore at the 2008 SAG Awards.

One basic fashion design rule for glamorous eveningwear is to balance colors. If there's going to a muted color, there should also be a flashy or dramatic color.

Christina's very stylish sequined gown has lots of glittery silver from top to bottom with the taupe.

It's a beautiful fit for her hips, bust, and waist.
