So what size was Marilyn Monroe actually? Luckily, many of her dresses, carefully preserved, are still around to measure off of. Further, one of her dress makers also chimed in with exact measurements he took. Those measurements were 5 ft. 5.5 inches tall; 35 inch bust; 22 inch waist (approximately 2-3 inches less than the average American woman in the 1950s and 12 inches less than average today); and 35 inch hips, with a bra size of 36D. Her weight fluctuated a bit through her career, usually rising in times of depression and falling back to her normal thereafter, but her dressmaker listed her as 118 pounds and the Hollywood studios tended to list her between 115-120 lbs.
