Traditionally, women's buttonholes are on the right side of their clothing, while men's buttonholes are on the left side.

The buttonhole placement was designed for the servants' ease.Know More
Another theory of the differing buttonhole placement is that a woman and man, seated by one another in a carriage, could see into one another's shirts. Horizontal buttonholes and proper placement help reduce gaps. For women, one buttonhole should be placed at the fullest part of their bustline with the remaining buttonholes spaced evenly and closely together.
