General business casual here, about 99% of the time (kakis, or cargo pants, usually in some standard tan, beige, or dark blue or grey). In warm months, I wear knit "golf" shirts, collared of course. In the winter, some sort of long sleeve something with a collar (Columbia makes decent l/s shirts that aren't terribly expensive), usually with a solid white under shirt. My shoes are moccasin style, slip off, tug on - usually like a NuBuc or real leather type (brown) - they've been some style of Merrills for about 10 years now. This makes removal easier for those that don't allow shoes in their homes (military town, full of Asian folks) or for those homesites where there's more mud than sod.
I don't wear shorts to work, even in NC's hot summers (except on those rare "office days"). I will wear newer, clean, fresh jeans to empty foreclosure properties, certainly when the weather is bad - but stick with my Merrill footwear and "golf shirts" regardless of the pants situation.
I also make sure not to wear any outerwear that has a team or person (like a specific race car driver) on or about it - no need to whiz off some seller or refier because s/he doesn't like my favorite college team or NASCAR driver. I will occasionally wear a ball cap to an empty foreclosure, one that may have bugs in it that could hide in my hair (fleas/ticks/whatever). I keep my hair cut to "high and tight" so that if I do wear a cap to one appointment (for the above reasons) I can remove it and show no signs of "hat head" for any occupied homes I have to do the reast of the day. I do have a Gore Tex boonie-syle hat I will wear, oustide, during downpours, regardless of the occupancy situation. I will also wear that hat at empty homes in mid-summer, as it is also SPF 60 (and I keep my hair short short). On really, really cold days, I have a skull-cap beanie (newer style toboggan) that I'll wear on the exterior to keep my ears from freezing and turning bright red.
I also keep my jewelry to a minimum (wedding band and a "cheaper watch"). Don't want anyone thinking that appraising makes us rich, 'cause it don't. I don't like it when guys, especially, come to my home for something wearing guady (even if real) gold bracelets and chains - reaks of a used car salesman or worse, a used car financier. I also don't do earrings - as should no male over about 22-23 that expects to be taken seriously outside of a music group.
