duet brides who got video

i am trying to pick songs....it says i need songs for preparation, Formal, and highlights.

what is formal?

i have no clue what songs to pick bc i dont know what that section includes.

It def differs from bride to bride cause my friend used them also and hers was a bit diffrent....for us formal started with the receiving line at the church then on to all pics inside and outside the church...us arriving at thr rh..all formal pics there,ch and us right before we were called in to the reception...it was long but I think they did it that way cause we picked a long song and they used the whole song...we picked this is the time by billy joel...and its my fav part of how they did the video...


As for my friends video...she picked a song and her formal went only up till ch then duet picked a song for ch untill reception.....hth
