Buttonholes for fastening or closing clothing with buttons appeared first in Germany during the 13th century.3 They soon became widespread with the rise of snug-fitting garments in 13th- and 14th-century Europe.
Buttonholes often have a bar of stitches at either side of them. This is a row of perpendicular hand or machine stitching to reinforce the raw edges of the fabric, and to prevent it from fraying.4
Traditionally, men's clothing buttonholes are on the left side, and women's clothing buttonholes are on the right.5 The lore of this 'opposite' sides buttoning is that the practice came into being as 'women of means' had chamber maids who dressed them. So as not to confuse the poor chamber maids, the wealthy began having women's garments made with the buttons and holes 'switched'; the birth of the modern ladies' blouse. The chamber maids themselves, as did most all the common class, both male and female, actually wore 'shirts' with buttons and holes placed as on men's clothing. There appears to be no concrete reference to prove or disprove this story, but its plausibility bears noting.67
Sewing machines offer various levels of automation to creating plain buttonholes. When made by machine, the slit between the sides of the buttonhole is opened after the stitching is completed.11
