Well, just in case, 'everyone' does not know my view on it, I will present it as others continue to repeatedly share their views on the same or similar outward appearance subjects. I think sometimes the more 'conservative' Anabaptists are more outspoken on such things, whereas those labelled more 'liberal' (which, by the way, make up the larger number of Anabaptists) are not in Anabaptist churches that have 'some form of standards' pertaining to outward appearance to adhere to.
Unless one considers a form of church standard would include an unwritten requirement, for example, of a person serving in a church leading role in a bathing suit. My guess is that an usher would stop such a thing at the door. In the MB church I attended people dressed as they would going to most any event outside the church (young men wearing ball style lettered caps sometimes worn backwards, women wearing pants, dyed hair, long hair, short hair, makeup, men in summer shorts, various forms of jewelry, tatoos, etc). I seldom today would see a man wearing a suit and tie which, years ago, was an expected norm, the 'Sunday best' expectation. When it comes to facial hair, no written or unwritten church standards were expected.
In our society, whether or not a man has facial hair is not a defining characteristic of being a man nor was it at various times in history. Actually many gay men wear beards. Myself, I wear a beard and moustache. Here is an article on why a Christian man should wear a beard and his arguments supporting wearing one -
I think he makes some interesting observations but I am not convinced a church needs to make standards for it.
