Lively wore a peach gown designed by Michael Kors for the red-carpet appearance.
The dress had long sleeves, a drop-waist skirt with pleats, and a purple-and-white floral print from top to bottom.
The black dress was asymmetrical with a single strap reaching across one shoulder, and another thin piece across Lively’s back.
She made the classic outfit even more glamorous by adding layers of diamond bracelets and matching drop earrings.
Designed by Atelier Versace, her vibrant blue gown was covered in silver beads from its off-the-shoulder strap to its long skirt, which had a thigh-high slit.
The dress also had a thin slit below its neckline and a long train that flowed behind the actor.
Carolina Herrera created her black-and-white midi dress, which had a leather-bustier bodice and a chic tulle skirt. The latter was crafted from sheer white fabric, and decorated with black flowers and petals.
When Lively turned and posed for photos on the red carpet, her dress highlighted her baby bump.
Her sequined midi dress was designed by Retrofête with a daring slit on the right side of its skirt and a matching belt tied loosely above her baby bump.
For accessories, Lively chose diamond bracelets, multicolored rings, and pastel heels.
Valentino designed her long-sleeved minidress, which was sheer aside from its rows of silver sequins.
Lively completed the look with a thin white scarf around her neck, a matching headband, golden hoop earrings, and platform heels.
Lively presented her husband, Ryan Reynolds, with the American Cinematheque Award on Thursday in a flowing floral dress with a plunging neckline.
The “A Simple Favor” actress paired the dress with stacked leather and jeweled bangles and turquoise and silver drop earrings. Lively’s simple, swooping hairstyle drew attention to her earth-toned accessories.
