Painful Tiaras

My junior prom is coming up, and I've got my date and dress. Now I'm deciding on the perfect hairstyle, which I think will be a smooth, simple updo. I want to dress it up with a tiara, but the last time I wore one (Halloween) it was such an uncomfortable experience. It was a silver one from The Icing (store kind of like Claire's boutique) that looked pretty enough, but felt like Jesus' crown of thorns after about an hour. Since this is the prom, I'm willing to spend a little more money on a beautiful yet comfortable tiara. Comfortable tiara? Am I on crack or does one actually exist? If anybody has tried or knows of any tiaras which do not cause painful headaches, your advice would be very appreciated.
