Is a tiara/necklace/veil too much?

I finally picked up my dress, and I’m so excited about the dress (lots of pictures because I’m in love with it!!). But I’m really torn about what to do for accessories. I definitely will be wearing my grandmothers sapphire earrings (fairly big studs), but I’m not sure whether a tiara or other hairpiece, veil, and necklace would be too much based on the detail in the dress. It’s hard to see in the pictures, but the dress has lace, sequins, and beading (quite possible I’m a bit over the top...).


The girl at the store thought maybe only a plain veil and a necklace, but I’m worried the necklace will take away from the detail in the dress and hair pieces (tiara or decorative comb and a plain veil) would be less distracting... what do you think? Do I need a necklace? Or will hair jewelry be enough? And is a tiara too over the top for the dress?
