THIS TIME OF YEAR, I live by the simple sartorial rule that more is more. Every party and get-together is my very own red-carpet moment, and I go for it! Bright jewel tones, twinkling embellishments, gilded trimmings, lacy overlays. After all, if not now, when? The holiday season invites liberal accessorizing, so even if it's just another day at the office, dress up your wardrobe workhorses with all the blingy jewelry you reserve for special occasions.
