Under the Regency masked balls were instituted at the Opera. At these public functions, safeguarded by the practically impenetrable disguise of a domino, all classes of society mixed indiscriminately. If tales of the time are to be believed, many a gallant has shadowed a domino the entire evening, only to make the humiliating discovery that the coquettish countess of his dreams was a tripe-seller from the market. With the fall of the French monarchy the domino degenerated into an abuse, and was finally abolished, excepting for such occasions as carnivals and fancy-dress balls. The dominoes worn by women differ from those worn by men in that they invariably manage to strike a distinguishing feminine note. The textures employed are lighter, being usually soft satin, silk, or mousseline de soie. The hood, instead of partaking of the severity of a cowl, is round in shape and, for most festive occasions, is trimmed with fluffy frills of silk, chiffon, and lace, further elaboration consisting of flowers. A characteristic example is of forget-me-not-hued bengaline lined with pale pink. The yoke sparkles with silver sequins and the round hood and shallow cape display frills powdered with glittering paillettes, and reveal inner frills of frayed pink silk and cobwebby lace the tint of old ivory, a bunch of shaded roses being fastened near the left temple and another at the throat. At the foot is a flounce which, when the wearer walks, shows occasional glimpses of pink silk and cream lace, and the wide sleeves bear sequin-embroidered cuffs and lace ruffles. A quaint domino is of gauze of an opaque whiteness, strewn with black and gold spots of varying sizes, the hood gathered up in the middle beneath a big white poppy, the petals tipped with gold and the centre of black silk.
