Hmm. Off the top of my head, we will put money and a baby in a bed before the wedding, there won't be any bridesmaids or groomsmen (we will only have 2 koumparoi - 1 koumparos and 1 koumpari). Because the wedding is in Greece, I will wait outside of the church for her and everyone will stand outside with me. Her dad will drop her off in a car then she'll walk up to me, and we'll walk into the church together with everyone following behind. There will also be no flower girl or ring bearer.. we have paranifakia (young girls who walk with the bride) who will walk with my SO and hold the train of her dress, and paragamproi (young boys who walk with the groom) whole will follow behind me.
Also, the wedding will start late in the afternoon (after 5pm).
At the reception the first song to be played will be miroloi (a lament) - it's our version of a moment of silence and it is always done as the first song of wedding receptions. Additionally, we will have a band and you can request songs to be played for you or someone else - when you request a song played for you or someone else, you usually give the band money as a tip. Also, it's tradition to shower the band with money by throwing up a lot of bills around the band, so that's going to happen too.
