Procession order

It can be you and your FH if you like. It might just be your father or both parents alongside you -- if the aisle is wide enough. If not wide enough, you could have honored family go before you and your FH. Once you include these options, you already are just going on some basic ideas who you want to give special attention to -- even if they just take front row seats. This still becomes a way of honoring the transition into marriage.

It might be more unconventional to have the FH's parents in the procession.
