The tiara is a bit wide for my head, but I was still able to wear it without it sliding around or falling off or anything. Also, the tiara, which I ordered for myself for Christmas, is absolutely beautiful!! Not only does it brighten my day - literally and figuratively -, but it also makes me feel more confident as well as like royalty. It's perfect! I don't know when exactly, but I'll definitely purchase from this site again! Thank you!
