The study methodology selected those describing the maja and majo among the figure paintings, portraits and genre paintings by Goya that identify unique characteristics with the qualitative analysis of the cases of the upward flow with that affect the costume of the upper classes. The influence of the majo and maja costumes were outstanding in the shape of the outfits while the French style gown of the upper class women were one-piece dresses in shape, those of the maja were two-piece dresses that consisted of the upper and gather skirts. The costume was perfected by use of the mantilla or head kerchief, instead of the headdresses prevalent at those times. The majo''s costume affected the men''s costume of the upper classes in the shape of the outfits. Short coat and tight breeches were preferred to the loose ones as well as instead of a long coat. Rather than the wigs or tri-corn hat, the head kerchief and sash belt applied, which could be evidence of the upward flow as well as shows proof of the influence of majo and maja costumes.
