He just wore the vest... he does have the jacket to go with it (which he wore at our catholic ceremony here at home!). I don't think he was too bad... honestly it was a warm day, but probably the best day weather wise that we had the whole time we were there. I thought we'd be sweating buckets but where our ceremony was shaded and there was a breeze it wasn't too bad... my legs were pretty hot though haha! Mark didn't complain too much about sweating though! I love the vest look! It looks soo good to me and he did roll his sleeves up after we did our formal photos!
Honestly we had the most wonderful time and I think everyone else did as well! We didn't have one complaint while we were there and everyone loved our ceremony and we had a lot of people tell us it was the best wedding they had been to!
I think if he wore a jacket he would have been really really hot... but if they just wore it for the ceremony maybe it won't be so bad?
