Here in S.F. I'm seeing more guys jogging in traditional 70's & 80's style running shorts instead of those long baggy "Pajama Pants".
If you like the old shorts, here's a simple way to bring them back: A bunch of guys across in cities all across the country (and the world for that matter) should just decide to start running/jogging in them and evenetually the fad will catch on. The same goes for wearing speedos for swimming.
You might also email clothing makers urging them to start marketing short shorts as "Men's Wear" too. In ads and stores, the traditional shorts are displayed only in the "women's wear" section. However the "men's wear" section has only the long, baggy pajama style.
Paraphrasing from the Obama campaign, If you want change, speak up!!!
