When I’m at a nice European beach, I wear a pair of Vilebrequin briefs, an indulgence from a few years ago. I also have Speedos, but usually wear boxer trunks that I buy from Nordstrom. One is a Norwegian brand and the other is a pinkish cotton. I’m probably too old for the Speedos, but I’m a workout addict and have a 32” waist, so I guess it works for me.
