Feeling that Wonder Woman moment? Surely forehead bands will soon become de rigueur (Jennifer Behr’s metal headband, above right, is almost there; $805, net-a-porter.com). In the meantime, power up with a bold forearm cuff such as this one from Chufy (above left, $1275, matchesfashion.com). Sass & Bide has long done a good line in so-called “urban tribal” pieces and their bodice harnesses are a key accessory (sassandbide. com). For the main event, how about this Maticevski dress (pictured, $1799, tonimaticevski.com) with its powerful shoulder line and slashed sleeves? Just the ticket for exercising your superpowers in the boardroom or the cocktail party.
