The Beard Stays

first its the beard, next its your friends, next you will be carrying a european man bag and using moisturizer on your hands !

I've seen it happen

been there done that....

You may want to consider shaving a little before that. Take it from me, your neck will be very uncomfortable even with a small amount of perspiration; it will be even worse with a tux collar or uncomfortable even if you're not sweating.

You may want to consider shaving a few days in advance if you currently don't shave regularly. Then gently shaving the night before the wedding (as long as your hair doesn't grow so fast that you have a five o'clock shadow at noon.

Agreed . Take it down to stubble with a trimmer about 24 hours before shaving. Let the skin adjust to the shock

All joking aside, congratulations!
