We came across this collection of hats on Zazzle.
This raises and interesting point: why is chlorine your perfume? OK, we get it--The smell of chlorine is a pleasant reminder of the pool. It can bring about memories of a good swim or hard work in the pool.
But... that chlorine "perfume" means that you are still covered in chlorine. And chlorine is terrible for your hair and skin. You are better off leaving the chlorine in the pool and letting your body have a break in between swims.
