Flowers or tiara in my hair?

I can't decide what to do with my wedding hair. I have naturally blonde hair that is up to my shoulderblades. I am considering wearing it half up and already have a veil. Would it be overkill to have a few orchids wound in my hair on top of the veil? Or should I go with a tiara? The wedding is indoors on April 17th in NY, where it is still pretty chilly so part of me feels like flowers would look silly since it is not a summer, beach, or outdoor wedding. Any advice? Thanks!
