undercover - I did exactly the same once, I went on holiday and came back with a beard. The difference was I was school overseer at the time and also had a part the same night on the service meeting. I shaved it off for the following Sunday meeting but that didn't stop one elder sounding off at me. I simply told him that not having a beard had more to do with right wing American sterotypes than any Biblical command, so we agreed to leave it at that.
In the early 70's I was counseled for wearing my hair 1 inch over my ears - hardly long haired hippy style. I just wish I had that amount of hair now a days!
I think that was those were the only times in 50 years growing up in and in the truth I ever received any real 'counsel'. No wonder it was a shock to many when I suddenly just quit going.
