So um.. What do I wear??

So you get an invitation to your best pal's wedding.. it's an outdoor August affair starting mid afternoon.. no specifications on attire. What do you wear?

Here are a few tips from msn lifestyle.. hopefully this will help shed some light on what you should plan on wearing to your next grand affair.

The invite says: "White Tie"
This is the most formal of all wedding dress codes (think the Oscars). He should wear: A tuxedo, a long black jacket with tails, a white pique vest, and a bow tie. Black, formal shoes and even white gloves for dancing are appropriate. She should wear: A formal, full-length ball gown in a neutral color like dark brown or black. Glamorous makeup and dramatic jewelry and hair are appropriate.

The invite says: "Black Tie"

She should wear: A chic cocktail dress or a long evening gown in a dark, neutral color like brown or black. The bride, wedding party, or friends can help answer questions about the appropriate dress length.

The invite says: "Formal" or "Black Tie Optional"
The wording here suggests something slightly less formal than black tie. This means that a tuxedo isn't required but the event is still formal enough for one to be appropriate.He should wear: A tuxedo or a formal dark suit and tie.She should wear: A long dress, a dressy suit, or a formal cocktail-length dress in a dark, neutral tone like brown, gray, or black.

Makeup and hair can be natural and everyday.

The invite says: "Semiformal" or "Dressy Casual"
