I agree with the above comments. I have certainly never seen a man wearing a sporran with regular street clothes. When I was in Paris on sabbatical in the early 1980s, though, there was a fashion fad that consisted of using sealskin dress sporrans as women's shoulder bags. The sporrans were sold in many boutiques as "bourses écossaises" (Scottish purses) and I saw many women carrying them with the waist strap used as an adjustable shoulder strap. When I returned to Paris six years later, the fad was over and I didn't see a single one.
