Thanks to Jon who told me about a pair of cool sweatpants offered by teen clothing catalog, Alloy.
The Reversible Sweatpant (item#163923) is white with a repeating black line drawing of a girl with a Series III Lambretta. It reverses to a plain background with a singe large image of the girl & scooter. The sweats range in sizes (S-XXXL)and price ($26.50 - $29.50).
Ladies, be sure to bookmark Alloy.com and check it periodically for scooter stuff.Every once in a while, they offer scooter products or use scooters in their catalogs.
