ADROVER’S NEXT SHOW: Once the wunderkind of New York’s fashion world, Miguel Adrover, whose company skyrocketed in the Ninenties and bottomed out financially in 2004, is now the subject of a new documentary. The Majorcan designer will fly into New York April 17 for the first U.S. screening of “Call it a Balance in the Unbalance” at Pratt Institute’s Brooklyn campus. After the show, Adrover will chat with Pratt Fashion Chair Jennifer Minniti about the highs and lows of his career. When the Costume Institute’s “Punk: Chaos to Couture” bows in May, Adrover’s designs will be among those featured in the exhibition.
