I'm going to be wearing a tux for a wedding reception this weekend...I don't feel any pain for you. Tuxes are no more uncomfortable than conventional suits...and they make your shoulders look HUGE. I like the way I look in a tux.
pony up and get a designer tux... everyone should own one. Buy it post season you can probably get a hi designer tux for less thatn 1k. It will last u forever.
