Join Wonderwall.com as we take a look back at the best and worst fashion moments from the 2021 Venice Film Festival, starting with this showstopper from Jennifer Lopez… J.Lo pulled out all the stops to make her red carpet debut with her back-on beau, Ben Affleck, at the premiere of his film "The Last Duel" on Sept. 10. The singer-actress was a vision in white in a sleeveless Georges Hobeika gown featuring a plunging neckline with Swarovski crystal embellishments and a thigh-high slit. She accessorized with silver Jimmy Choo peep-toe heels and Cartier jewels.

Jodie Comer brought the dreaded sheer-skirt trend to the 2021 Venice Film Festival premiere of "The Last Duel" on Sept. 10. The "Killing Eve" actress's black Alaia turtleneck dress didn't just feature a sheer pleated skirt, though: It also featured an asymmetrically sheer top that exposed half of her flesh-toned bra. She completed her disappointing look with heeled boots also from the fashion house's spring 2022 collection.

A night and day difference! Jodie Comer donned a darling Louis Vuitton ensemble — an ultra-feminine black maxi-skirt and a structured sleeveless top featuring pearl and floral embellishments — at the 2021 Venice Film Festival photocall for "The Last Duel" on Sept. 10.
Penelope Cruz donned this silver brocade off-the-shoulder Chanel dress to pick up her award for best actress during the 2021 Venice Film Festival closing ceremony on Sept. 11. Sadly, between the drop waist and the random tulle at the hem, this look was far from award-worthy…
Wow! Cynthia Erivo left little to the imagination in a sheer Oscar de la Renta dress with strategically placed floral embellishments during the 2021 Venice Film Festival closing ceremony on Sept. 11.
Maggie Gyllenhaal rarely manages to impress us with her sartorial selections (more on that later!) but we absolutely loved the loose-fitting Proenza Schouler creation she wore to pick up her award for best screenplay during the 2021 Venice Film Festival closing ceremony on Sept. 11. Her black pumps paired perfectly with the black-and-green attached bralette that peeked out of the extra-long arm holes and at the collar.
Olivia Culpo's proportions were all thrown off by the strapless column dress she donned at the amfAR gala during the 2021 Venice Film Festival on Sept. 10. The extremely unflattering frock featured a feathered peplum drop waist that might've worked if it were either higher up or lower down. She fared much better the previous day…
Olivia Culpo knocked it out of the park in a green PINKO gown featuring sheer mint panels alongside lacy emerald panels on the skirt during the 2021 Venice Film Festival premiere of "America Latina" on Sept. 9. She completed her look with chain-link Pomellato pieces: a choker, drop earrings, a bracelet and even a ring.
Sarah Gadon looked pretty in pink in a spaghetti-strap Valentino dress with an oversized midriff cut-out during the 2021 Venice Film Festival closing ceremony on Sept. 11.
Zendaya wowed at the Venice Film Festival premiere of her film "Dune" on Sept. 3. The talented beauty sported a custom flesh-toned leather gown by Balmain that featured a perfectly fitted silhouette (made with an exact model of her bust!) with strategic draping. The skirt portion was equally exquisite with its thigh-high slit and delicate train detail. She paired the unique frock with perfectly matching pumps and added jaw-dropping accessories and an equally standout beauty look…
When it came time to style her hair, Zendaya opted for an artfully slicked-back style. This helped put her Bulgari jewels on display — pieces from the brand's new Magnifica High Jewelry Collection that included a serpent-shaped necklace with diamonds and emeralds. She also rocked simple diamond studs and a matching ring from the jeweler…
Zendaya added a beautiful emerald and diamond ring to complete her fleet of Bulgari jewels, which all together totaled 131.56 carats of emeralds and 62.69 carats of diamonds.
A vision in red! Kate Hudson selected this show-stopping Valentino confection from the brand's Resort 22 collection for the "Mona Lisa and the Blood Moon" premiere on Sept. 5 during the 2021 Venice Film Festival. The frothy tulle gown included romantic (and strategically placed!) lace details including a high neck, resulting in a standout silhouette. But unfortunately, not all of Kate's Venice Film Festival looks were hits…
Next to that phenomenal Valentino moment, the frock that Kate Hudson wore to the "Mona Lisa and the Blood Moon" photocall on Sept. 5 pales in comparison. The star wore this tan Dior long-sleeved top underneath a linen dress in a similar shade for a minimalist and forgettable look that was nearly the polar opposite of her premiere ensemble. Despite the dull dress, the star managed to have some fun posing for photos…
Kate Hudson's Dior dress certainly made for an interesting prop! Unfortunately, when the actress pulled up her skirt, she also revealed its unfinished hemline and the wrinkles in its linen fabric.
We adored the color of Anya Taylor-Joy's hot pink satin number at the Venice Film Festival premiere of her film "Last Night in Soho" on Sept. 4, but she lost us with the hat! The actress's neon Dior design — complete with short sleeves, a bow detail at the waist and matching pointy-toe pumps — was lovely, but her strange headwear sent this look south.
A fascinator? Yep, Anya Taylor-Joy opted to accessorize her gorgeous Dior gown with a matching small woven hat covered in netting and an equally unique diamond necklace with a leaf motif.
Anya Taylor-Joy's "Last Night in Soho" photocall ensemble on Sept. 4 was a totally different story! We loved the floral-print spaghetti-strapped Rodarte dress she donned along with a matching shawl. From the faux-vintage feel with that all-over print to the way she paired it with silver Giuseppe Zanotti sandals and equally whimsical jewels (which we'll see next!), we adored this look.
Anya Taylor-Joy added some fun silver ball earrings from Tiffany & Co. to complete her look at the "Last Night in Soho" photocall.
Black-and-white beauty! Penelope Cruz wowed at the "Parallel Mothers" premiere on Sept. 2 during the Venice Film Festival. The star arrived in this Chanel gown — which featured sweet ruffled straps and an ecru silk tulle ruffled petticoat — that came straight from the fashion house's 2021 couture collection. Let's see the fun and feminine look from another angle next…
Penelope Cruz's Chanel confection was even more glorious from this angle, which showed off the low-back detail and embroidery. When it came time to add a little sparkle, she tapped Chanel fine jewelry for accessories. See some of her fabulous jewels next…
Check out that bracelet! Penelope Cruz accessorized with an 18-karat white gold bracelet with diamonds from Chanel's Cafe Society collection and a massive "curved feather" 18-karat white gold and diamond ring. Next up? The diamonds on her ears…
Penelope Cruz completed her all-Chanel ensemble with these stunning diamond earrings from the fashion house's Plume de Chanel collection.
Kristen Stewart arrived at the Venice Film Festival premiere of "Spencer" on Sept. 3 in these unlikely coordinates. Though we loved the shade, we weren't fans of the Chanel pairing — which included a mint green minidress with a black velvet bow detail at the waist paired with sheer trousers in a similar shade. Though both pieces included lace trim to tie things together, the pants seemed unnecessary and just didn't pair well with her stark white pumps.
Cynthia Erivo scored a fashion miss at the Venice Film Festival premiere of "Dune" on Sept. 3 in this Schiaparelli confection. The frock included a silver metallic top with some seriously over-the-top sleeves, a fitted ankle-length black skirt and a yellow silk belt to tie everything together. Paired with platform shoes, it all felt a little too dramatic for our taste.
The always fashion-forward Timothee Chalamet arrived at the Venice Film Festival premiere of his film "Dune" on Sept. 3 in this sleek Haider Ackermann getup. The heartthrob actor sported a fitted sweater and matching trousers all embellished with black sequined beading. He rocked a white collarless blouse underneath plus black boots and a few other accessories, which we'll see next…
Timothee Chalamet added a few silver rings to the mix when it came time to accessorize his sleek Haider Ackermann separates.
Yikes! Maude Apatow's "Competencia Oficial" premiere look at the Venice Film Festival on Sept. 4 included a dramatic purple flower at the neckline and a crazy amount of ruffles down the tiered column skirt. Her Armani Prive frock felt like an odd choice for the young star.
Looking sharp, Dakota Johnson! The star rocked a fitted Gucci pantsuit at the photocall for "The Lost Daughter" on Sept. 3 and skipped an undershirt, instead opting to sport a black bandeau underneath the coordinates. She completed the look with strappy black sandals.
Not all pantsuits are created equal! Maggie Gyllenhaal attended that same event — the photocall for "The Lost Daughter" on Sept. 3 — in this disastrous look from Schiaparelli. The oversized jacket with gold hardware looked comical when paired with wide-legged trousers, making this ill-fitting getup appear to be something the star borrowed at the last minute.
Barbara Palvin sported this structured Armani Prive design at the "Parallel Mothers" premiere during the Venice Film Festival on Sept. 1. The strapless confection included a peplum detail at the waist that flowed over top a column-style skirt for a memorable silhouette and stunning red carpet moment.
Barbara Palvin added a dramatic cat eye, edgy black and diamond drop earrings and a funky updo to complete her Armani Prive red carpet moment.
With some pretty over-the-top fashion at the Venice Film Festival, Hailee Steinfeld's pick at the "Competencia Oficial" premiere on Sept. 4 fell flat. The star wore this Armani Prive gown from 2006 featuring a plunging neckline and thigh-high center slit, all subtly altered from its runway appearance a decade and a half ago. The black beading, lace and crystals underwhelmed when compared to some of the fabulous fashion in Venice.
Fabulous! Tiffany Haddish channeled Old Hollywood glam in this stunning black-and-white Christian Siriano gown that she wore to the premiere of "The Card Counter" during the Venice Film Festival on Sept. 2. The design started with a structured strapless white bodice before giving way to a mermaid-style black skirt. When it came time to add a little sparkle, she tapped Pomellato for some eye-catching jewels…
Tiffany Haddish added a chain-link silver necklace and matching drop earrings as well as a chain-link ring for the big occasion — all from Pomellato's Catene collection.
