What's the briefest you can wear in British pools?

[Bede735]

For about the last 20 years I've worn nothing but Speedos with a 5 cm (2 in) side seam. I'm usually the only guy at my pool who wears anything that brief, bur I'm so used to it, it doesn't bother me. At the moment I wear Speedo endurance briefs, which are getting close to needing replacing, but unfortunately Speedo no longer manufactures 5 cm briefs.

So - I've ordered an Aussiebum 1.5 (4 cm) Classic, which is briefer than I've worn before, but I like the look of it. What would be deeply embarrassing is if some pool attendant ordered me out of the pool for wearing something too brief, so as I say, are Aussiebums within acceptable limits?

Having said, women attend my pool wearing bikinis with string sides and nobody bats an eyelid.
