People are going to be judgmental anywhere you go. Friends, if they truly are that, should accept you for who you are. I'm bald as a result of brain cancer years ago (10 yrs in remission) and initially some people that didn't know why I was bald gave me gruff about it.
Now I know that as long as I am happy, life is too short to worry what everyone else thinks. I just finished a full sleeve on my right arm. I have grown my beard out, and also just got my ears pierced (10ga) 4 days ago ..im 42 and happy and life is good.
I say go for it. If the in-laws don't like it.. well... they're family by association anyway.
