My buddy had us rent tuxes from The Black Tux, and I was skeptical at first that the tux would not fit right without me being measured by someone in person, but I was very wrong. The tux fit great and looked even better. The shoes were nice and comfortable as well. I felt good in my tux because the fit was right. The price was comparable to in-store tux rental as well. You just send in your measurements and wait for your tux to arrive.
I would highly recommend using this company if you have people in your wedding who are in a different location and can't all meet at one tux rental shop.
Bottom Line: Yes, I would recommend this to a friend
