Don't waste time

Men's tuxedo rental prices/styles are pretty much the same price no matter where you go.

Make sure to avoid going to rent/see tuxedos during prom season.

Makeup test

Find a makeup and hair vendor that will do a trial for you. This way you'll have enough time to make any adjustments months before the wedding.

Talk about the Bachelor party and the Bachelorette party

As future husband and wife you need to get off on the right foot. In some cases the Bachelor/Bachelorette party may not a big deal, but don't assume. Make sure to discuss your feelings with each other and be sensitive to each others feelings. At the same time a little wiggle room and having a sense of humor will make this Bachelor/Bachelorette party go smoothly.

Dance, Dance, Dance

If you partner can't dance and you can, make sure you teach them a step or two. Even better if you can't dance surprise your future mate with some new moves. There are plenty of places to take private lessons, and if that won't work amzazon.com sells tons of DVDs.
