Black Dresses for every occasion
The Occasion: A Wedding
Old etiquette: Don't wear white or black or red.
New etiquette: Black and red are perfectly fine, but white is still the ultimate wedding no-no.
What to wear: Let the invitation, the season, and the hour be your guides. (If you're at a loss and you're close to the bride, ask her what's right; otherwise, consult the maid of honor or the bride's mother.)
