Found, at the local secondhand bookstore

This is fabulous enough as is, but found inside the book was an old magazine article on which fabrics to wear to achieve your perfected disco look:

"For a night at the roller disco, avoid loose fitting blouses and gaucho pants made of sateenlike materials, which tend to "flutter" as you skate.  Save these for the disco dance floor; their "bounce" and drape will complement your moves to the music."

Totally wicked advice.
