Teigen donned a lace two-piece by Zeynep Arcay for the occasion, which consisted of a backless halter top and matching midi-skirt over white ballerina briefs. She accessorized the chic outfit with a black belt, leather clutch and strappy heels.
Legend perfectly complemented his wife's look, clad in black pants, suede shoes and a patterned letterman jacket.
One night earlier, Teigen attended Glamour magazine's pre-Women of the Year Awards dinner, where she also opted for white. The Lip Sync Battle co-host stunned in a cleavage-baring pantsuit, which she styled with a similar black belt, box clutch and white jacket.
Last week, Legend couldn't stop gushing over Teigen and their seven-month-old daughter, Luna. "Family at sunset," the "All of Me" singer captioned a stunning snap of his picture-perfect family gazing at a beautiful cotton candy sky.
When ET caught up with Legend in October, he revealed what life has been like since he and Teigen welcomed their little bundle of joy. "We just try and make every day as great as we can for her," he dished. "Help her grow into the kind of human we want her to be, and try and make every moment as stress-free and joyous for her as possible."
