Methylene blue was first prepared in 1876 by German chemist Heinrich Caro. It is used as a dye in microbiology and as a redox indicator in analytical chemistry among others. It has also been described as the first fully synthetic drug used in medicine. It was not well liked by patients as it turned their urine and sclera blue. On the other hand the deep blue colour is perfect for a cheerful and practical dress.
