Bathing in Brighton and what I found in my Regency research.
It wasn't a foreign concept for Regency people to enjoy the beach. Their method just differed from what we do today. Note the full clothing from head to toe! And those houses that roll into the water-Bathing Houses where you could change in complete privacy and bathe in equal privacy. Or, if you weren't into sea bathing, your sensibilities weren't offended by those who wished to.
