Dark Blonde Girl Posing In Summer Swimsuit Costumes

Penelope Byrde points out that Smollett’s description may not be accurate, for he describes a two-piece costume, not the one piece shift or smock that most people describe and is depicted in contemporary prints. His description does, however, tally with Elizabeth Grant’s description of the guide’s costume at Ramsgate in 1811. The only difference is in the fabric the costumes are made of. Flannel, however, was a common fabric for sea bathing costumes as many believed the warmer fabric was necessary in cold water.
In the 18th century women wore "bathing gowns" in the water; these were long dresses of fabrics that would not become transparent when wet, with weights sewn into the hems so that they would not rise up in the water. The men's swim suit, a rather form-fitting wool garment with long sleeves and legs similar to long underwear, was developed and would change little for a century.
In the 19th century, the woman's two piece suit became common—the two pieces being a gown from shoulder to knees plus a set of trousers with leggings going down to the ankles.
In the Victorian era, popular beach resorts were commonly equipped with bathing machines designed to avoid the exposure of people in swimsuits, especially to people of the opposite sex.
