Ok knotties, I need an opinion on whether I should wear a necklace with my dress. I only have 5 days left so answer quick 

See the attached picture and please ignore the fact that I look like a 12 year old when I have my hair up and no makeup on. 
I will be wearing small dangly earrings and a tennis bracelet. I am leaning towards no necklace but wanted to get extra opinions!
