The Ladies' Book of Etiquette, and Manual of Politeness

The riding-dress, or habit, is best made to fit the figure tightly, with tight sleeves. It may be open in the front, over a neatly fitting chemisette, or buttoned close to the throat, with a neat linen collar and cuffs. The loose sacque is ungraceful, but a basque is most becoming on horseback. Gauntlet gloves, of leather, are the most suitable, and must be loose enough to give your hand perfect freedom, yet not so loose as to interfere with its motions. Do not wear the skirt too long; it will be dangerous in case of accident, and it may prove annoying to your horse. Your habit must be made of a material sufficiently heavy to hang gracefully, and not move too much with the wind. For a winter habit, a warmly-lined basque, trimmed at the throat and hands with fur, is an elegant and appropriate dress, and a round cap of the same cloth as the habit, with a band, and pieces to cover the ears, of fur to match the dress trimmings, makes a handsome and appropriate dress. In summer, your hat should be of fine straw, and slouched to shade the face; in winter, of felt, or, if you prefer, a close cap of cloth. The hat may be trimmed with feathers or knots of ribbon, and the shape should be one to protect the complexion, at the same time graceful and becoming. Avoid any display in a riding dress. Choose a material of some dark or neutral tint, and never use showy trimmings.
