I bought Kiniki Brazil Swim Brief White Swimwear in 2013.

I wore them in France last year, even on the beach near the Jules Ferry Centre which is in the news at the moment.
Kiniki tend to be a little old fashioned with very high waists etc, but good value and fun.
It has a drawstring, which it needs when swimming in the sea.
