The first Japanese to adopt Western clothing were officers and men of some units of the shōgun's army and navy; sometime in the 1850s, these men adopted woolen uniforms worn by the English marines stationed at Yokohama. Wool was difficult to produce domestically, with the cloth having to be imported. Outside of the military, other early adoptions of Western dress were mostly within the public sector, and typically entirely male, with women continuing to wear kimono both inside and outside of the home, and men changing into the kimono usually within the home for comfort.
