Putting to one side the fact that it's the most absurd and unmanly garment,

[Burney]

One cannot imagine that it would be beyond the wit of man to fit the garment with some sort of opening at the front designed to allow egress to the pénis and enable micturation; perhaps this idea could be further rolled out to, you know, trousers?

Possibly, but I think that still misses the larger point of perineal chafing.

I think such garments are fine on young ladies, of course. They like a ludicrously impractical garment, the birds do.
