9 of Blake Lively's best Cannes Film Festival outfits, and 6 that missed the mark

Blake Lively's first red-carpet moment at the Cannes Film Festival wasn't her strongest.

She wore a burgundy gown designed by Gucci, with a halter panel over its strapless bodysuit and a high slit across its skirt.

The dress was accessorized perfectly with Lorraine Schwartz jewelry and sparkling Casadei sandals. But because of its color and column shape, the look didn't stand out on the red carpet — it blended in.

But she returned the next day in one of her best outfits to date.

The outfit in question was a sleeveless, sparkle-covered dress from Chanel.

Its iridescent design had halter straps with a V-shaped neckline and a fitted waistband that extended into a semi-sheer midi skirt with pockets.

Lively completed the look with Sophia Webster heels and Lorraine Schwartz jewelry.

The crystal-covered minidress she wore to a Chopard event that year was cute and fun.

You don't always see miniskirts at the Cannes Film Festival or its many after-parties. But if anyone can make it work, it's the "Gossip Girl" actor.

She wore a Giambattista Valli design crafted from white, floral lace and embellished from top to bottom with pink crystals.

And as always, Lively added matching jewelry to enhance the dress' sparkle effect. 

And the black-and-white gown she wore to the "Captives" premiere was even better.

The strapless Gucci design had a black bodice that was lined with white fabric across its neckline, and the same material wrapped around the back to create a full skirt.

The dramatic dress made a statement on its own, but Lively always knows how to take her outfits up a notch.

This time, she added diamond jewelry, red lipstick, matching nail polish, and a sleek bun.

Lively missed the mark with her pink coat when she arrived at the festival that year.

Her black trousers, wide-brimmed hat, and loafers with tassel detailing were a chic yet comfortable way to arrive at the film festival.

Her magenta coat, however, looked more like a night robe than a winter jacket.

But the white ensemble she wore when arriving in 2016 was ideal for a trip to France.

Her trench coat perfectly matched her white trousers, and her brown sandals added a coastal vibe to her look.

Lively also carried a black woven tote bag and wore minimal makeup.

The actor perfected French fashion at a photo-call for her film "The Shallows."

Wearing Giambattista Valli again, Lively looked like she stepped off a French runway in this white minidress.

Its textured miniskirt was embellished with a black velvet belt, and its satin top was decorated with gold beads. It also had unique, cape-style sleeves that wrapped around Lively's shoulders and chest with a beaded buckle in the middle.

She completed the look with black-and-white striped pumps. 

But the red outfit she wore for a "Cafe Society" photo-call wasn't as memorable.

Lively posed for photographers in a red Juan Carlos Obando jumpsuit, which was sleeveless and had a belt loosely tied at the waist.

Red is definitely Lively's color, but the outfit wasn't as iconic or daring as other looks she wore throughout the festival.

The sparkling gown Lively wore to the "Cafe Society" premiere that year was the perfect mix of glamour and boldness.

The actor's Atelier Versace gown matched her skin tone and was covered in cutouts, which created a "naked" effect.

But it was also decorated with sparkling panels and cascading crystals down its skirt, which matched the glamorous vibe of the film festival.

And her sparkling blue gown from the "BFG" premiere has become an iconic Cannes fashion moment.

Most of Lively's outfits at the 2016 Cannes Film Festival didn't plainly reveal her baby bump.

Though people speculated, as she told Vogue, it wasn't until she wore this blue Atelier Versace gown that they started to confirm their suspicions.

The gown was fully covered in beads that sparkled in the light, from its single off-the-shoulder strap to its floor-length skirt that flowed behind her into a train.

But the pastel gown she wore to the "Slack Bay (Ma Loute)" premiere didn't measure up to her previous looks.

Her powder-blue gown, which had a full ruffled skirt and flower-embellished bodice, was a Vivienne Westwood Couture creation.

Though the dress might have worked in another setting, it looked a bit juvenile on the Cannes red carpet — especially when paired with a messy bun and printed heels.

The dress Lively wore to a press luncheon for "Cafe Society" was cute, but its yellow shade washed her out.

The sleeveless Valentino look was made from velvet, with crisscross straps as a belt around her waist and extra fabric hanging across the chest.

However, the red, white, and blue outfit she wore to a Vanity Fair dinner was striking.

Not only did it match the national colors of France, but the mixed prints and sparkling textures made it show-stopping.

She wore a red-and-white striped minidress underneath a sequin-covered coat lined with red, white, and blue flowers along the hem and sleeves.

She wore a cutout dress on a different day of the 2016 festival, and it wasn't her best.

Lively styled the dress well, adding strappy heels and dark jewelry that added some edge to her look.

But it's tough to look past the garment's sporadic cutouts, which appear more distracting than daring.

She looked more comfortable in the black, coat-style gown she'd donned a few days earlier.

Her Salvatore Ferragamo coatdress had a plunging neckline that reached her waist, and thick rows of black feathers that lined its sleeves and skirts.

She wore it with clear, Cinderella-esque heels and stud earrings.
