What to wear to a wedding?

Dressing for a wedding or special event - it is important to be properly dressed for any special occasion. Remember, just like an interview: you ONLY have 1 chance to make a good first impression! Don’t be too creative to stand out! Pictures will be taken at the wedding, and you don’t want to look at your friend’s pictures a year from now and wonder: What was I thinking (dressed like that)?
• Informal Daytime: Dress shirt and pants, preferably a sports jacket.
• Informal Evening: Suit
• Semi-Formal Daytime: Suit
• Semi-Formal Evening: Dark suit
• Formal Daytime: Dark suit and tie
• Formal Evening: Tuxedo (if invitation states "black tie") or dark suits.
• Ultra-formal Evening or White Tie: White tie, cummerbund or vest and shirt.
Do's and Don'ts
• Don't try to be experimental with a tuxedo. A black tuxedo with white shirt and black bow tie or four in hand tie is always the best choice. If "Creative Black Tie" is used on the invitation, then wearing a tuxedo, vest and black shirt, with no tie, might be acceptable. Also, trendier cities like Los Angeles and New York might be more accepting of going with a trendier look.
• Wear a dark suit, with a tie if the wedding is after 6 PM, and doesn't say "Black Tie."
• Don't wear a tuxedo during the day time, regardless of the formality of the event.
• Do use a conservative outfit, if the invitation doesn't specify a dress code for the event. A dark suit and conservative tie will be appropriate for any occasion.
