Come on in! The waters well warm!
Seriosly, how do your custies expect you to earn aliving?
If you don't come regularly then maybe you won't be there at all in the future. It probably helps that I'm cheap & cheerful.
When I take on a custy, I let them know I shall be there all weathers. It's there from the start.
I wear a lght Dri as a Bone coat over shorts, t shirt & open sandals. Plus a leather wide brimmed hat. I never feel wet & as I said, the waters warm!
