Tux for FH

About how long before the wedding to grooms typically go for their tuxes?

I have been concentrating so much on me, I forgot about him!

I forgot about that too! One night he said to me do you think its possible if we squeeze some time into figure out what I am wearing! This was just about a month ago and I am getting married 4/17. When I went the lady told us that everyone just needed to meausured 3 weeks prior to the wedding.
