I learned something interesting that applies here: one of the reasons why Hashem spread us through all the countries is so we can take the customs / culture / mannerisms is the country and elevate them by using them in a holy connect (obviously only in a way that is fine halachically.)
That would definitely apply to the attire of the chosson mentioned above, or the way the tables are set, and could apply to the way they come in as well – unless it’s not very Aidel…
A friend of my husband told him not to come in with me to the woman’s section because it’s not a Jewish thing and not Aidel, and so we posed together just outside the door, unfortunately the photographer missed it, and just got me standing there myself
