She is Required to Choose the White House China
A task started by First Lady Mary Todd Lincoln in 1861, the First Lady is required to pick out the White House china pattern to be used during her husband’s administration. As the First Family is frequently entertaining politicians, celebrities, and other important figures in society, fancy china for formal dining occasions is a must. First Lady Mamie Eisenhower even saw to the completion of a room that houses and celebrates the china patterns picked out and used by every administration in the White House, preserving them as a part of history.
This is one of the wilder First Lady rules we know of.
