What is appropriate to wear to a beach wedding in December?

Its for a friends wedding and it is being held in Cancun. Suggestions for guys and girls would be great, cause my girlfriend is stumped on what to wear as well. The wedding is on the beach, so I'm guessing its pretty casual. Thanks in advance!

What is appropriate to wear to a beach wedding in December?
For a guy...





Khaki pants, white polo shirt, flip-flops.





For a girl...





Any kind of sundress in a light color (not black, but definately not white!), flip-flops, or some cute strappy flats. If it is in the sand, you will want open shoes, and heals would get annoying.





Have fun!!!
Reply:Linen pants and shirt for the gentleman and a linen sun dress for the lady. Classy and casual. Shoes, no need, your at the beach. I've been to many a beach wedding. This is the protocal. Have fun.
Reply:Depending on the weather, perhaps a lacy, pastel color dress, a nice hat (if she wants) and instead of shoes or sandals how about barefoot for the ladies. For a man I think a nice cotton shirt (any color) and kaki shorts would look nice. Perhaps the guys can wear sandals or even go barefoot. Maybe as an accessory everyone can blow bubbles while at the wedding so it will look very nice (water and bubbles).
Reply:any nice dress will do. summery ones are fine since its at the beach. find a cute shorter dress. one that is casual, yet appropriate. and wear dressy sandals with it. Have fun! Beach weddings are beautiful!
