Mamie Eisenhower wore Pink
The US presidential inauguration of Dwight D. Eisenhower in 1953 when Eisenhower’s wife Mamie Eisenhower wore a pink dress as her inaugural gown is thought to have been a key turning point to the association of pink as a color associated with girls. Mamie’s strong liking of pink led to the public association with pink being a color that “ladylike women wear.” The 1957 American musical Funny Face also played a role in cementing the color’s association with women.

The transition to pink as a sexually differentiating color for girls occurred gradually, through the selective process of the marketplace, in the 1930s and 40s. In the 1920s, some groups had been describing pink as a masculine color, an equivalent of the red that was considered to be for men, but lighter for boys. But stores nonetheless found that people were increasingly choosing to buy pink for girls, and blue for boys, until this became an accepted norm in the 1940s.
