What a revelation: pink was once a masculine color for boys and blue for girls. Take a look at this pink-trimmed sailor suit from the Smithsonian’s online exhibit HistoryWired. “…the generally accepted rule is pink for the boy and blue for the girl. The reason is that pink being a more decided and stronger color is more suitable for the boy; while blue, which is more delicate and dainty, is prettier for the girl.” Have we flip-flopped back yet?
