A woman whose sex appeal and looks blossom at an
age when most women's allure is fading.
Not quite the same as a
MILF, because a MILF may well have been known for her attractiveness in her youth or before she had a child.
A vorderman is a woman who was once regarded as
average, dowdy, bookish or nerdy, who abruptly turns into Mrs. Robinson type figure for younger men (or women).
Named after British TV presenter, Carol Vorderman.
