Like most of life, this is a matter of taste and preference, but I prefer a more subtle approach ... I do like the sign on an easel, especially if it can be located near the entrance ... I then try to find a nice reachable spot to place a business card holder ... Also, an 8 x 10 copy of my business card placed in a frame set up where I am playing works well... One place I worked, I set up at the keyboard end of a baby grand, and had the card holder sitting on the piano (right next to a LARGE snifter shaped vase that was PERFECT for tips) ...
Getting back to the skirt, if it is plain and has no 'writing' on it, you can adjust it for the proper height whether sitting or standing ......
