1. CeremoniesThe FLOTUS’ fashion choices are a subject of never-ending fascination and scrutiny, but none more so than her Inauguration evening wear. And this year, although she took a few hits for selecting another Jason Wu gown—a rich ruby-red halter, as opposed to 2009’s ethereal white one-shoulder Inaugural style—she earned major huzzahs for her bold diamond jewels, courtesy of in-demand designer Kimberly McDonald. Not only did Mrs. O don McDonald’s signature geode-outline diamond earrings and bangles with natural color mixed-cut diamonds, but she also wore a custom diamond-embellished gold ring, which cinched the neckline of Wu’s velvet and chiffon confection. The edgy jewels provided the perfect counterpoint to the gown’s soft, flowing fabric—and, for a few hours at least, everyone stopped critiquing the first lady’s bangs.Diamond bangle; price on request; Kimberl
