Hi! I am going to a formal evening wedding soon and need to finalize my jewelry choices within 2 days... going shopping today. My dress is black velvet burnout with a low v neck. My hair is very short. I was planning to only wear statement earrings but now i think i need a large necklace to balance out my hips ... i looked at rhinestones but once you get into more statement sizes they seem so costumey... open to other ideas. Is it ok to go a little more casual with my jewelry? Thanks!

ETA - i am not sure what the more casual option would be... but not sure rhinestones are the way to go. I dont want to spend a lot.
