The secret to Kaia Gerber‘s beauty is subtle elegance. The model, who stepped out in New York City in a sparkling black dress on Thursday night, spent once again that sometimes simplicity is best. To raise funds for a nonprofit bone marrow donor center, she attended the DKMS 30th anniversary gala in a dress designed by Marc Jacobs covered in a texture that gave it a sparkling effect. Kaia wore luxury jewels from Tiffany & Co. The model left her hair loose as she posed on the red carpet at DKMS 30th Anniversary Gala at Cipriani Wall Street in New York City.
