I do volunteer ministry in a number of mainline facilities in my town.  I assist a large variety of mainline pastors who come to do weekly Sunday night worship at a large local retirement home. I see a wide variety of professional ministers in this capacity.  It is shocking how many of them not only appear sloppy but who correspondingly turn-out to also be unprepared, unorganized, and unfamiliar with the needs of the particular audience, etc.  A friend of mine, who is a retired-minister's wife, is always dressed neatly in a professional manner.  Her hair is always done, nice makeup, and attractive clothes.  It never screams "I spent 2 hours and thousands of dollars to look like this."  It doesn't scream, "I am outclassing you" -- it is more quiet and understated than that.  But she DOES look like an inviting person to talk to -- everyone instantly feels drawn to her.  She and her husband have both figured-out how to walk the line between looking professional enough to be credible and trustworthy, yet offering a public image that instantly makes people feel comfortable and almost like an instant friend with them.  They both have had 50 years' practice at successfully looking gracefully approachable, based on a belief that they have something valuable to offer to others and want to make it as easy as possible for others to connect with them.  The quietly professional look also gives credit to the fact that they earned the knowledge and experience sufficient to be able to offer ministry to others.  -- anyone can wear torn jeans or shorts, but that doesn't mean they are able to offer positive or helpful ministry.  A lot of the UCC Revs. put years and years of training into becoming ordained and prepared to help individuals and groups or churches find an ongoing spiritual path -- and then those same pastors try to downplay the intensive financial and personal investment they've dedicated to the effort to be able to help people -- and try to not use the "Rev." or otherwise try to get people to pretend they're not highly trained.  That really doesn't do credit to what the pastor has earned for him/herself.  (And by the way, I work in a UCC reg. office where the regional minister has a dirty joke up his sleeve for anytime people freak out when they discover he's a Rev.  But he also always looks neat and clean and respectable enough to be approachable and helpful to everyone -- even on his days off.)  And yes, as an example -- one of my fondest memories my whole life was the retired minister at our church's horsemanship camp, who like the rest of us, was sitting around a smoky campfire at night in our dirty cowboy clothes after a 14-hour day in the dirt and sweaty horses -- reading I Corinthians 13 to us, under the stars.  But if it's not horse camp, I would rather do day-to-day ministry with my friend, the retired-minister's wife.   You are a person of value, and each person you meet is a person of value, and your demeanor & ministry towards them should convey that -- and our subconscious minds, where our spirituality is housed -- is what sizes-up the msg. others convey in their appearance.  As "Clinton & Stacy" say, if you want people to respond to you a certain way, don't wear clothes that give off the opposite msg.:  if you have clothes for dirty housechores, don't present them to others during the 95% of the time when you're not doing dirtyhouse chores!
