Hairstyles for weddings?

I am HORRIBLE with hair. I can’t curl it and I stopped straightening it months ago. I have naturally curly hair and tend to leave it down, apply some moose, and let it be. I need super easy hairstyles that would be appropriate to wear to a formal wedding. I feel like leaving my hair down like I do every day wouldn’t be right to wear to a super formal wedding. Any ideas would help.
