Shorts without underwear? I also tried that when travelling in India, back in the 1980s. Much cooler, for sure, but in other respects it had its drawbacks.
I remember being sat on bus and having a delightful young woman take the seat beside me. Indian women, of course, are very good looking (or they were in those days when invariably they were lithe and fine-featured). Naturally, I glanced sideways to discreetly take-in her appearance. But, on doing so, I was rather taken aback to notice that the direction of her gaze was both downwards and diagonal. I followed the trajectory and there, to my acute embarrassment, I found that my rather too short shorts had an escapee... or rather several. From that day on I returned, greatly abashed, to more conventional dress.
Of course in your day, shorts went right down the thigh. I guess that only the most remarkably well-endowed could have had an accident such as I had.
