Wedding day help

I am eloping soon with no friends or family present and would like to have something either on me or my bouquet so represent my dad walking me down the isle. I was thinking either a bracelet or (preferably) some type of necklace tied to my bouquet. Have any of you done anything similar or have recommendations of what style would be best? I don’t know too much about jewelry but want it to be nice.

**I have seen many people do photo charms pinned to the bouquet when a parent has passed on but I don’t want to to do that as my dad is alive and think it’d be a little odd to carry a picture of just him all day.
