Open Question: What jewelry/accessories should I wear ?

I need to decide which items of jewlry to wear for my prom in July. Everything is matching diamante;
Headband/Tiara,
Earrings,
Necklace,
Bracelet,
Ring,
Sparkly Clutchbag.
Obviously I cant wear all at the same time, but which ones should I wear?!
Thanks x
