how it fits

This afternoon I was at Davies Symphony Hall, viewing a performance by organist Chelsea Chen. She was wearing an asymmetrical dress with only one shoulder strap. The organ is a big instrument, and requires a lot of movement to play: the lifting and pulling and crossing over of arms, the swinging of legs and tapping of feet. I thought of the small tests I run in fitting rooms, lifting my knees, sitting and standing repeatedly, trying to gauge whether a skirt or dress will be easy to bike in. I wonder what strange fitting room contortions professional organists go through, stretching and bending in tiny spaces, trying to see if the fabric will tear here or chafe there, before purchasing a dress for performance.
