A 19th century
cartoon from
Punch showing men's and children's
sea bathing swimsuits of the time. The caption reads, "Now then, Mossoo, your Form is of the Manliest Beauty, and you are altogether a most attractive Object; but you've stood there long enough. So jump in and have done with it!" Although swimwear from that era was quite modest, it was very common for men to swim naked when away from women in the UK.
