I do!
In practice I wear the old Asic Tigers, the Gable version. I got them out of a box in the storage area.
We recently gave our kids the old warmups from back in the early 80's. You know, the one's that have collars and flair pants. The kids wear them on meet days at school and I wore one for the heck of it last semester.
In reality, I would love to have a retro dual, equipped with white on white, gum sole tigers, calf socks, nylon singlets, high thigh version, with terrycloth robes. Over the PA we would play "Hungry for Heaven" by Dio. Our headgears would still have the chin cups.
That would be awesome.
