Wear simple black clothes and some sophisticated costume jewelry. If you don't have any, visit a thrift store. Make sure that any necklace you choose doesn't scratch your accordion.

When you play accordion, people look at your hands a lot. Make sure your nails look nice and wear at least one ring. It lifts your heart to glance down at your own fingers and see a pretty ring gleaming upon them.

Do you wear make-up? Even if you don't, at least wear some lipstick. To many people, lipstick makes a woman real. I've never been comfortable with make-up, but I felt better about it when an expert said that the color of your make-up should be just a bit more intense than your own, natural colors. That made sense to me.
