Are wedding tiara's tacky?

Hi lovely, I don't think so but it depends on the tiara. Some can look cheap so it depends on the tiara in question. Please have a look at my range of bridal jewellery and headwear: https://www.angelina-alvarez.com/collections/bridal-wedding-jewellery-online

I think with the right dress that a wedding tiara is beautiful and elegant. I can't remember ever seeing a tacky tiara :-)
