What colors should you not wear to a wedding?
White, ivory, and anything that photographs as bridal - plus the wedding party's colors and, at some cultural ceremonies, red or black.
The firm rule is anything that reads as bridal: white, ivory, cream, and pale champagne or blush shades that look white in photos. That includes white-based prints with small patterns - if the dominant impression is white, skip it. Second rule: do not match the wedding party. If you know the bridesmaids are in sage, pick something else; matching reads as trying to join the party. Cultural considerations: red is the bridal color in Chinese and Indian traditions, so avoid a full red outfit at those ceremonies; white and black carry mourning associations in some East Asian contexts. Everything else - including black at Western weddings - is fair game. The one-minute test: hold the outfit up and ask, could anyone possibly confuse this with a bride or bridesmaid? If yes, change.
