Here I sit in my office, reading the thread on interview suits, dressed in a collarless pull-down shirt and a pair of clean, new jeans. I'm not dealing with anybody from the public today, so I dressed down; normally, I'd at least be wearing khakis. Folks are fairly casual around here, although we'll get a bit more dessed up when we have a public meeting.
I noticed that the day-to-day dress of planners varies from region to region, and also depends on the type of agency one works for. Based on my experience, county government agencies tend to be very casual and informal, where casual business attire (khakis and a tie for a men; the stereotypical "blue shirt planner" we make fun of on here) are requried dress in municipal plannng agencies. Planners working for economic development agencies wear their interview suits to work every day.
County and municipal planning agencies in non-big city areas in the Rocky Mountain region usually have one "cowboy planner," a crusty but sharp curmudgeons who dress in well-worn ranchwear.
Here's a typical county planning agency.
Here's a typical municipal agency planner's planner.
There's the economic development agency, in the class A office space down the street.
Of course, there's the planning department for Smithenwesson County, Montana. "So, yer puttin' the $#%&@ pole barn over there, right?"
