I’d have to go with Jackie.
While Jackie did have the corner on glamour, it came at an enormous price of rumored to have been a million dollars in 1960s money for a designer wardrobe. JFK's father was said to have paid her "hush money" to preserve his son's political career and keep her married to Jack despite his numerous affairs.
The Washington newspapers frequently reported criticisms of her spending behavior, materialism and elitism; and and tradespeople who worked in the White House at the time gossiped about her "hangers-on" in the White House whose decadent behavior supposedly revolted JFK, such as a poet who made little cuts on his wrists and dipped his pen in the blood to write his poems. I heard that and other stories as someone who grew up in DC, and whose congregation and family members worked in trades such as chauffeuring, Secret Service and painting contractors to the WH. Working-class people, while invisible to elitists, still have eyes and ears.
She was the first FLOTUS since Mary Todd Lincoln (who was known to be mentally ill, apparently with bipolar disorder) to spend lavishly on her wardrobe and on big-name designers. The public at the time chattered about Jackie's un-American aspirations to European aristocracy, which she then demonstrated by marrying billionaire Aristotle Onassis, who, however rich, also was unfaithful to her. Only after her divorce from Onassis did she redeem herself, as a caring widowed mother with a job as an editor in NYC. Her daughter seems to have both feet on the ground; yet her son took up the torch of narcissisim, decadence and privilege and paid with his life, and that of his bride.
