7 of the best maternity looks Blake Lively has ever worn

Blake Lively publicly showed her maternity style for the first time at a 2014 benefit event.

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.

A few days later, she hit a red carpet in a pastel-yellow maternity gown with a plunging neckline.

Her Gucci dress showed the more daring side of Lively's pregnancy fashion.

Its thin fabric hugged her body, and its deep neckline was decorated with a thick band of silver crystals. For accessories, the actor wore multiple diamond rings and yellow crystal earrings.

Days before giving birth, the actor wore a backless, form-fitting gown at a L'Oreal Paris event.

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.

In 2016, Lively attended the Cannes Film Festival in a stunning gown that showed her baby bump — though she hadn't formally announced her second pregnancy yet.

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.

She took an edgier approach the following month at "The Shallows" premiere.

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.

To announce her third pregnancy, Lively attended the "Pokémon Detective Pikachu" premiere in a sparkling yellow gown.

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.

Then in September of this year, Lively channeled the '60s with a maternity minidress.

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.
