The designer who dressed first lady Melania Trump for her official White House portrait is the target of social media trolls and the label is firing back. Trump's third wife wore a Dolce & Gabbana blazer, leading Stefano Gabbana to proudly declare, "Beautiful" and "Thank You" on Instagram. His post lit up with comments like "How can you?" and "You've lost a follower." But the designer was not backing down, telling critics, "Go to hell!" Dolce & Gabbana is one of Mrs. Trump's favorite designers.
