conundrum with swimming gear

ok.. Im a big guy.. 300lbs.. normal swim gear just does not seem to exist for an my size.

I can wear Zoggs size 42 ok.. but I really need jammers. The zoggs I have are hip racers.. which aren't a real good look.. and I ain't going the way of briefs !!

has anyone had luck with swimwear my size ? (has to cope with chlorine big time)
