Here's American fashion designer Oleg Cassini's 1960s predictions for what fashionable garb might consist of in the year 2,000. The outfit's leotard would feature wires encircling the bosoms and a radiotelephone attached to the belt buckle, wired to earphones and antenna in the hood.
"The suit will be temperature controlled," Cassini explained. "There is a battery under the bosom which controls the warmth needed."
I'll leave you to wonder why bosom batteries never took off.
