Swim Cap Tan Line

Hey guys and gals, I have come across a problem that I think affects everyone who wears a cap and swims outside, a forehead tan line. This is my first summer actually swimming outside full time, so I'm not sure what to do. I would just not wear a cap, but because of issues with my ears, I am permanently required to wear ear plugs (I have permanent scarring on my inner ear and going below four or five feet is too painful). My question to you all is, is there a way to not wear a swim cap, wear ear plugs without them falling out, and not looking weird? Any suggestions are appreciated! Thanks! Alex
