Get the marilyn monroe syndrome mug.
A condition that delusional fat women suffer from, whereby they cite that Marilyn Monroe was a size 16, proving that beauty standards have changed, and therefore fat is beautiful. Unbeknownst to them is that the sizes of clothing in Monroe's time were measured differently and a size 16 in the 1950s was roughly equivalent to a size 8. In reality, Monroe weighed about 120 pounds.
