hair and nails for prom?

so prom is about a month away i have no idea what would go with my dress. i was thinking maybe light gray nails with a glitter accent nail? not sure if that would match though. i was also thinking about doing waves for my hair! but if anybody has some suggestions and thinks something would look better please help me out and let me know! also any suggestions for jewelry? i’m not very good with styling things lol
