These blue Frescobol Carioca swim shorts feature the two tone Tidal print, a narrow waistband with adjustable buttoned straps at the sides, a concealed front fly fastening, side pockets and a buttoned welt pocket at the back. They say that the gentle flapping of a butterfly’s wings can eventually cause a tidal wave thousands of miles away. Well, here we are. The Frescobol Carioca wave is breaking.
