I find it interesting how something so little like a ring, could symbolize a whole concept such as marriage. Even so that without it, one feels that they have no proof that they're married..like Orlando. This relates to a theme of identity/gender. For a woman to be classified as "married" she needs proof, and for a ring, a female accessory to symbolize so is an example of how "the clothes wear us, we don't wear them" saying--goes back to the question of whether gender determines identity or the other way around.
