We aren't using Men's Wearhouse for our Tuxedos, but my DBil did last summer for his. A few tips I have if you use them since I had to go with DH for his is have the guys pick up the tuxes near them and have them try everything on a day or two before they leave incase sizing is wrong or something is missing, etc. instead of picking it up in Orlando(you can always return them to the store in Orlando). My DBil wanted everyone picking up their tux's in PA where his wedding was the day before and there wouldn't have been time for anything to get changed if it was not right.
The Shiny Brown Tux shoes do not match the tux at all. If your your colors are chocolate brown tux with latte vest and ties, it is hideous. Not trying to give anyone a change of heart, but after seeing my DH wear that for his brother's wedding as BM, I wanted to throw up. He looked awful in it and I begged my DBil to let him change out of it ASAP b/c I wouldn't take a single pic with my hubby in that hideous tux.
For ours either we're having the guys buy their tuxedos from a website I can't recall right now that the whole cost for everything is cheaper than 1 tux rental at Men's Wearhouse, or we're thinking of a Tuxedo Alternative that looks equally as nice.
Good luck with MW. They can be difficult to deal with.
