bathing beauties or adult-swim

From around the mid-eighteenth century through the Victoria Era, females wanting to take the sea air and enjoy a day at the beach were wheeled out past the maddening crowd of potentially gawking and leering males in personal stage-coaches, as Presurfer informs.
Etiquette and modesty (though these rules were recent impositions and far different from the practise of mixed skinny-dipping) dictated dictated that women bathers would enter a mobile changing booth, “bathing machines,” in formal street garb and disrobe, doffing her dress in for an equally concealing swim-suit and in the shallows, be allowed to frolic on a tether or at the strong hand of attendant. After this experience, the swimmer would be escorted back, drying off and donning her street clothes again for the sake of decorum. Maybe this production is less showy and less inclusive than a burkini.
