Could a bride wear pearls to her wedding?

You should always ask the Bride as it's her decision. There are times a bride will give her Maid of Honor and Bridesmaids a gift of a necklace and earrings. If the necklace is say your mothers or grandmothers and it means a lot to you to wear it then express this to the Bride and if she is mature enough she will have no problem with it.
