The concept of power dressing was born in the early 1980s, during the heyday of big shoulder pads and boxy suits to deemphasize femininity. Typically the style was accompanied by jewellery that was discreet, if at all. Even in the most conservative environments today, dress codes have become less rigid. The cut and colour of the suit might be sober and grey, but that doesn’t mean the jewellery has to be. From the upcoming Jewels Online sale, these totemic pieces exert strength, polish, and individuality.
