The Balmain x H&M show–meets–Backstreet Boys concert wasn’t the only party that happened this week. Everyone from Amy Schumer to Mary J. Blige celebrated women in Hollywood with Elle, and at the Americans for Arts celebration, Lady Gaga was even moved to tears. And that was just on Monday. A few days later in New York, the Fashion Group International brought out Justin Timberlake, Meryl Streep, Diane Kruger, and Lanvin’s Alber Elbaz, who wore a pink bow tie. Over in L.A., T Magazine celebrated its inaugural Greats issue with coven members Kim Gordon and Carrie Brownstein, plus Solange, Kiernan Shipka, and Courtney Love.
