Beyoncé joined her husband, producer JAY-Z, at the London premiere of Netflix's The Harder They Fall, although she couldn't be spotted on the red carpet. Nevertheless, the multihyphenate posed for photos for her stylists K.J. Moody and Marni Senofonte, showing off her custom velvet gown from every angle. The look was crafted over the course of 10 full days by Albanian fashion brand Valdrin Sahiti and is made from silk and velvet fabric with Lycra on the interior corset. The team posted a shot of Bey in the final look on Instagram, referring to it as her favorite black dress — so unsurprisingly, it seems like she had her pick from many. "Dressing an icon is not about the dress, it's about the sparkle in her eyes while wearing your creation," Valdrin Sahiti told POPSUGAR of the collaboration. The outfit was complete with simple black sandals, a crystalized Judith Leiber clutch, sunglasses, and Lorraine Schwartz jewels. (Her pear drop earrings were 21 carats alone, but she also accessorized with two diamond rings from her go-to red carpet jeweler.)
