Then What WILL They Wear?

A few decades ago, Morris Bishop wrote “The Crusty Professor's Song” (also found here) about changes in university dress codes since the days of stand-up collars. It ends:

Maybe time will banish
Sweatshirts, dirty jeans
Maybe these will vanish
From collegiate scenes
Students will not wear
Dirty sweatshirts, dirty jeans
Jackets, coats, waist coats, vest
Caps and hats, garters, spats
Cuff-links, cuffs, tie-pins, ties
Stand-up collars, stand-up collars
Never any more.

Then what WILL they wear?

The answer turned out to be pajamas.

As for what will follow pajamas, I will quote Arthur C. Clarke:

I have no idea what it will be, and am in no great hurry to find out.
