Is this a good dress for a Semi-formal dance?

that dress is super cute. It's a tiny bit fancy so wear some little sweater or scarf that is colorful but not that formal. wear some flats or simple heals, and idk what u look like so i can't tell you that much more. but you'll be fine and look good. yeah, most of the girls will probably be in dresses or skirts and you'll look fine, the guys will probably wear what ever their mom makes them
