Young Brunette Girl Reveals Her Red Blouse On The Couch

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.
Tailoring provides a closer fit to the wearer's shape. This is achieved with sewing of features such as princess seams or darting in the waist and/or bust.
Blouses (and many women's shirts with buttons) usually have buttons reversed from that of men's shirts (except in the case of male military fatigues). That is, the buttons are normally on the wearer's left-hand and the buttonholes are on the right. The reasons for this are unclear, and while several theories exist none have conclusive evidence. Some suggest this custom was introduced by launderers so they could distinguish between women's and men's shirts. One theory purports that the tradition arose in the Middle Ages when one manner of manifesting wealth was by the number of buttons one wore. Another that the original design was based on armour which was designed so that a right-handed opponent would not catch their weapon in the seam and tear through, and also that a person could draw a weapon with their right-hand without catching it in a loose seam of their own clothes. Female servants were in charge of buttoning their mistress's gowns (since the buttons were usually in the back). They tired of attempting to deal with buttons that were, from their point of view, backwards and as such they started reversing the placement when making or repairing them. Another possible reason is so men can easily undo blouses as, from the front, buttons are on the same side as a man's shirt. One other theory is that women were normally dressed by their maids, while men dressed themselves. As such, women's blouses were designed so it could be easily buttoned by the maid but that of men were designed so it could be easily buttoned by the person wearing it.
Although in all the cases proposed the reasons for the distinction no longer exist, it continues out of custom or tradition.
