ladies I need advice

Barb
I have a wedding to go to this weekend but I don't know what to wear, it's going to snow and be cold and it's in the evening so I don't want to wear a dress but it's a wedding so I can't look bummy or to everyday casual, I want to wear pants but I don't have dressy pants only jeans and jeggings and leggings so what kind of outfits do you think I can put together that would be wedding guest worthy?
