The way Stacy/Izzy acted at the ceremony

How insane was it the way both Izzy and Stacy acted at the altar (before vows and yes/no) like he walked in waving at everyone with both hands. Then Stacy decides to say “it’s a lot of dress!” All of that made me realize she wasn’t taking it seriously as a real wedding. It’s like the kept breaking the 4th wall and it was totally weird to me. Sure, you should think your partner looks amazing walking down the aisle but you don’t need to make it all about that. They both were so unserious at the beginning, and I think they were both “in love” with the others looks and not much else.
