When we "work" here in Texas, we wear work clothes. Thats not to say that you can't look good. Starched bluejeans, boots, starched shirts and a hat ( for shade from the sun ). Dockers and golf shirts look more casual to us than starched jeans and shirts. Besides, dogs, barb wire fences, rose bushes, etc are awful hard on thin material, and the skin underneath. When it's 95-100 degrees in the summer and 20-30 degrees in the winter, you wear durable clothes. ( And we just might get 90degree days in Feb and 35degree days in April).
If you feel comfortable for the area you work, go for it. I suppose in Hawaii you could dress like Magnum PI., but not here. By the way, anyone need an appraiser in Hawaii???
Oh, and Bob, you keep stirring the pot, it's fun to see how many Appraisers still have a sense of humor!!
