Swimming costumes as we know them today began to be worn from the 1920s. In 1935, the Mayor of Port Macquarie noted it would be necessary for Council to ‘stop the habit of men rolling down their costumes to the waist and hips and walking about and sun-baking on the beach’. Council passed an amendment to the Ordinance regarding public bathing which included diagrams of suitable costumes. This men’s woollen knitted swimsuit made by Jantzen in the 1930s includes a low-cut singlet top and shorter legs with a modesty panel at the lower front.
