This tiara is the biggest one I've ever seen. I wear a 7 1/4 hat size. It is a little large for my head circumference but it adjusted nicely. It is lightweight too. I danced with it on all night and it never bothered me or moved. It is a beautiful piece. I'm extremely happy with this piece.
I was very disappointed when my first tiara arrived broken. However, the problem was very quickly addressed, and the item was replaced. The replacement arrived safe and sound, and I am very happy with the quality of the tiara, it is beautiful.
