In 1927, Time Magazine surveyed department stores to understand which colours these department stores associated with women in their clothing lines.
The results were quite mixed; some said blue, and some said pink.
The debate continued with nothing conclusive.
In 1939, WWII broke out, and there was a shortage of workforce.
Women joined the workforce producing war supplies, sometimes replacing men who had joined the military.
In factories, most women wore ordinarily styled blues.
The post-war era was a period of prosperity; everyone wanted to enjoy the comfort of their homes, and the keenness for a relaxed domestic life increased.
In 1953, Dwight Eisenhower – the General who had played a key role in winning WWII for the US – became the US President.
His wife, Mamie Eisenhower (First Lady), loved pink and was known for it; she decorated The White House with so much pink that the press started calling it the pink palace.
A lot of headlines in the press at that time mentioned the colour pink with her name.
She was the epitome of feminism at that time and explicitly mentioned her husband being her career.
Women, having seen too much of factories, took to this idea of feminism readily, and to be ladylike became being like Mamie Eisenhower, and therefore, being fond of pink.
Then some movies also showed glamorous women wearing pink (e.g., Marilyn Monroe in Gentlemen prefer blondes).
