Thank you to everyone who let me know about the no tux before 6 rule.
I had no idea when my FH made the reservation there was an issue w etiquette. :-/
Ceremony is 11:30 a.m. Reception is 12-5. So...
How major of an issue is it if groomsmen are in black tuxes from MW. He picked this model:

Should I have him switch the reservation:

Thank you in advance for all your support. I am in panic mode.
