The uniform was white shirt. Since it was a blue one, that is likely the stem of the "out of uniform" issue. Not much you can do about it now.

If anyone else wants to try this, make sure you stick to the "uniform" and only vary the pants with a kilt.

This is my problem at my job. The dress code does not say a kilt is not allowed. But it does say no bare skin. The code for skirts and dresses is the closest I can go with and it says I'd have to wear panty hose, or make sure kilt hose come above the knee, so no leg ever shows. Sorry, I refuse to wear panty hose!
