Even for Naeem Khan, whose work is so clearly targeted at those who frequent the red carpet and other oft-photographed spots, the lure of the sporty motif was just too strong to resist. The designer of dazzle sent out group after group of bugle-bead and sequin sweatshirts and T-shirts, some in multicolor florals, others in youthful bright yellow or blue flower patterns. There were also silk sweats and sheer-panel sweatshirts with explosions of crystals. With places like Brooklyn’s Barclays Center becoming cultural hubs and courtside getting serious paparazzi play, a pair of black sequin sweats might not be the weirdest thing. Nor the most practical.
