"The first one is _appropriateness_. Colors and forms and modes, in themselves graceful or beautiful, can become ungraceful and ridiculous simply through inappropriateness. The most lovely bonnet that the most approved _modiste_ can invent, if worn on the head of a coarse-faced Irishwoman bearing a market-basket on her arm, excites no emotion but that of the ludicrous. The most elegant and brilliant evening dress, if worn in the daytime in a railroad car, strikes every one with a sense of absurdity; whereas both these objects in appropriate associations would excite only the idea of beauty. So, a mode of dress obviously intended for driving strikes us as _outre_ in a parlor; and a parlor dress would no less shock our eyes on horseback. In short, the course of this principle through all varieties of form can easily be perceived. Besides appropriateness to time, place, and circumstances, there is appropriateness to age, position, and character. This is the foundation of all our ideas of professional propriety in costume. One would not like to see a clergyman in his external air and appointments resembling a gentleman of the turf; one would not wish a refined and modest scholar to wear the outward air of a fast fellow, or an aged and venerable statesman to appear with all the peculiarities of a young dandy. The flowers, feathers, and furbelows which a light-hearted young girl of seventeen embellishes by the airy grace with which she wears them, are simply ridiculous when transferred to the toilet of her serious, well-meaning mamma, who bears them about with an anxious face, merely because a loquacious milliner has assured her, with many protestations, that it is the fashion, and the only thing remaining for her to do. "There are, again, modes of dress in themselves very beautiful and very striking, which are peculiarly adapted to theatrical representation and to pictures, but the adoption of which as a part of unprofessional toilet produces a sense of incongruity. A mode of dress may be in perfect taste on the stage, that would be absurd in an evening party, absurd in the street, absurd, in short, everywhere else.
