Police detective here. A few of my brother offices have seen me formally kilted at scotch tastings, or fundrasing dinners, but I've not really worn it socially "with" them.

Those in the department that know I wear a kilt give me a fair amount of ribbing, but I return it in kind as I know it's all good natured. Personally, I think that's part of having a "masculine" job - flipping each other cr@p about, well, just about anything.
