Don't compare the fundoshi with the modern swim brief, it cannot compete with synthetic stretch fabrics and elastic.
It is better to compare it to Aunt Mable's drawers and bloomers from the Victorian era, the type of thing Mrs Grundy would approve of.

Compared to the one piece, full body, knitted wool swimsuits that people swam in up to the First World War, the fundoshi is a simple, elegant and efficient piece of swimwear.
