Contrast, brightness, and sparkle are your three best friends onstage. You need to contrast with the stage itself (if it's black, consider more than just a black costume), and your costume needs to have contrast within it to make you and your performance visible to the audience. So a good rule of thumb is that for a small restaurant type audience, or any performance in which you're close to the audience, subtle can be fine. But for the stage, it's contrast, bright colors, and/ or sparkle all the way.
