One day in 1912, Mrs. Witter, the president at Ewha School, came into sewing class with
a bundle of white fabric in her hands. The students all looked closer, wondering whatit was. Mrs. Witter began handing out the items in her hands to her students. It was a weird-looking
string made of white fabric. ¡°Okay students! Let¡¯s sew the string around the waist of
your underskirts.¡± The students were dumbfounded.
