Yes that is a good saving for the tux.
My dh is hard to fit so the extra charges for shortning, and adjusting. Amounted to a lot more then we expected. At least I'm shopping around for the shirts, studs & cuff links, tie, and vest. Cumber buns are not in this year. so we passed on them.
We have the Men's Wearhouse her in our city. The gave really good service and extra special perks.
We cruise many times so that is a plus to save on the rentals.
