I think my fiance would like my hair to sort of sparkle im not talking about glitter just nice hair piece or clips but I dont know what jewellery to wear on the day either or how it will match. Now I wont be wearing a veil and I dont really want a tiara I was just looking for suggestions of jewellery/hair bits that will compliment my dress. My hair will be about the same colour as what is in the picture.

Im not being lazy im still looking but im rubbish at making choices

Thank you
