I know what you're saying: if I'm not mistaken, my mom made my dad a pair of knickers to wear back in the '50s and '60s. They obviously weren't the specific uniform called for. But that was a different time. I know for a fact she sewed flags and put in washers as weights.
I disagree with you about TASO -- I don't like the stripe requirement myself, but I do agree that it may take a different style short to get everyone to buy and wear the SAME thing. We wear the same shirts, pants, hats, etc. Its also a small price to pay if we now can wear shorts in SV games early in the year.
