I have a particular item of clothing that I like to wear every time I play bass at our church services. I call it my bass sweater. it's a lightweight black pullover with fine white stripes on it. It seems to want to bond perfectly with my leather strap, so when I position my bass is stays there without shifting. Maybe there's a bit of superstition involved, but I seem to play better when I wear it. And I always have to jack up the right sleeve, it's always dragging on the strings.
