Representing the monarch's power and other attributes, a crown has become synonymous to romantic fantasy. Disney has a large contribution to that--but so do princesses like Grace Kelly, the Lady Diana and Kate Middleton. Fancy dress as royalty and you must pick a crown. Have a princess theme for your daughter's birthday and you need a crown or 20 of them
Speaking of 20, the British crown or half crown coin is a burst of nostalgia between your fingers.
