Blouses are historically a cask style, mostly mail-like garment, that were rarely part of the fashionable woman's wardrobe until the 1890s. Before that time, they were occasionally popular for informal wear by the peasants.
Blouses are often made of cotton or silk cloth and may or may not include a collar and sleeves. They are generally more tailored than simple knit tops, and may contain feminine details such as ruffles, a tie or a soft bow at the neck, or embroidered decorations.
All above pictures I post are the most classic blouses for women in the victoria era. They look gorgeous on them with their almost white color and sleeves.
