Misery, they say—or at least Shakespeare said—acquaints a man with strange bedfellows; and democracy acquaints a woman with strange costumes. The variety of “casual clothes” is limited only by the panorama of color and the ingenuity of the designer. Yet, whatever garments a woman may have chosen to put on, the probability is that she will wish to add to their harmony the grace notes of a jewel. Informal clothes are usually worn for informal hours, which naturally call for a touch of ornament. Festive occasions even more strongly suggest the glamour of jewels. Yet in no field are women more at a loss than in the etiquette of jewelry. Few need to inquire about the proper combinations of outfits and accessories. It is unnecessary to caution the young girl, putting on her first evening gown, that she must not wear her sport shoes. No more need her mother be told not to serve canapés wearing the kitchen apron she put on while preparing them. But when it comes to jewelry, to selecting the jewels that are appropriate to the occasion, most women have only the haziest idea. Yet if they discover that they are not adorned in keeping with the function, their day is clouded. _En Route_ In traveling, by plane or even by train for a weekend in the country, only tailored jewelry should be worn. Large diamond pieces are definitely out of bounds, even in the subdued hum of a dining car. I repeat that the one exception, now and forever, is the combination of the engagement ring and the wedding ring. This is always as appropriate as pleasant. _Country Weekend_ If the journey takes a woman to be a guest for the weekend, it is wise for her to ascertain her hostess’s plans. While there may be in store a restful time of relaxation, when one may make oneself at home and do as one wishes, it may also be that the hostess has made certain plans. She may have invited friends for a cocktail party, or a garden party, to meet the visitor. There may even be a formal dinner party in prospect, in honor of the guest—who must, of course, be prepared with clothes and with jewelry to match the occasion, and do her hostess justice. _The Garden Party_ Given in the summer, usually out of the city, a garden party is a lighthearted affair. Short dinner gowns, colorful cocktail dresses or separates are best enhanced by jewels of light texture. Jewelry of twisted gold wire conveys this effect; or the gold wire used as setting for diamond or pearls. Like the flowers in colorful profusion around, jewels with stones of different colors are in good taste, providing of course that the colors are in harmony. An all-white costume will not do justice to diamonds; if a woman looks attractive in white, she should wear with it colored stones or pearls. Sapphires, however, may be combined with diamonds, most pleasantly with a fair complexion; on a dark beauty there should be rubies and diamonds set in gold.
