De Paris died in a hospice in Arlington, Virginia near the US capital after a long illness, a friend of his, Dimasito Pereira, told AFP.
Another friend, Alain Trampoglieri, told AFP from France that de Paris had been diagnosed with a brain tumor two years ago.
But de Paris continued working at his Washington shop up until two months ago, said Pereira.
In his heyday, de Paris worked for Ronald Reagan, among others, who shared with de Paris some of his trademark jelly beans, and with Johnson, who introduced the suit maker to his wife and daughters.
