I arrived back from SW France on Sunday morning, whilst on the big open beaches, dunes and forests of the Gironde I swam, hiked and sunbathed in my light blue desmiit swim briefs:

And my Aussiebum ice blue WJ Classic 1.5. yes they go go rather see through in the sea, but no one minded:

There's enough space for everyone in SW France and no one minds what you do so long as you don't interferre with them. Short shorts are normal and wearing speedos and wet suits around the campsites to be expected.
Best wishes and loads of points to those who've made the effort to wear light blue swim briefs while I've been away.
