The wrist watch, for practical reasons, should not be worn on the handbag arm; the winding crown may be jarred or broken. For both practical and aesthetic reasons, it should not be worn with other bracelets. The glass may be jarred off. And while the watch bracelet may look attractive alone, the presence of other jewels makes its utilitarian function over-prominent. The wrist watch should be serviceable, but beautiful. In any case, a watch is at best an interloper, if not a downright intruder, in moments of feminine finery. Permitting a woman to espy the hour when she should not be so concerned, the watch—like all spies—should be as much as possible unnoticed and unknown. If it be worn, it should not be as a watch but as an integral part of a jewel. _In Front of Your Mirror_ A wise woman knows the importance of her jewels and does not squander them in overlavish display. The “principle of parsimony” applies here as elsewhere: unless there be an overriding reason for elaboration, the simplest means are the best. Jewels may, as we have seen, be beautiful on many parts of the body—but not on all of them at once. Each occasion, each costume, calls for separate consideration and individual selection of jewels. It is not vanity, but common sense, for a woman to spend time before a mirror, making her own acquaintance, becoming familiar with her qualities and with the values brought out by various arrangements of her jewels. Only by such a process, renewed frequently through the years (as jewels and features alter), can a woman command the full power of her treasure chest as a true ally to her own beauty. Daniel Webster, looking at the great stone face of the “Old Man of the Mountain,” observed: “Men hang out their signs indicative of their respective trades: shoemakers hang out a gigantic shoe; jewelers, a monster watch ... but up in the mountains of New Hampshire, God Almighty has hung out a sign to show that here He makes men.” And let them not mar themselves, Shakespeare reminds us, including the fair sex of the human kind. And a woman, whose sign is beauty, keeps a “monster watch” over her harmony in her jewels. Decorum and decoration, hand in hand, lead her to the fullest capture of the values with which nature has endowed her and which she has helped to foster, feed and bring to flower. PART THREE _The Etiquette of Wearing Jewels_ CHAPTER 11 _The Etiquette of Wearing Jewels_ The emphasis on “casual living,” in our day, does not destroy the need for more formal occasions. On the contrary, indeed, the woman who has been informal in various types of summer apparel may feel even more thrilled at the opportunity to put on an evening gown, with the appropriate jewelry. And what jewelry, she may well ask, should be worn in more relaxed and casual hours?
