Clinton had invited Lewinsky to a White House radio address, she recalled.
Besides being an activist, Monica is also a fashion designer and writer.
Clinton admitted that he did not have any sexual relationship with her on a nationally televised White House News conference.
Lewinsky went into detail about the day the piece of evidence was created, as she continued to carry on a years-long relationship with Clinton in the early months of 1997, after he won re-election.
Her confidant Linda Tripp encouraged her to keep it, with the dress proving a key piece of evidence after Clinton, who has been married to wife Hillary since 1975, denied any affair had taken place in 1998.
However, much information about their relationship is not available.
