Here Are the Absolute Sexiest Oscars Dresses of All Time

Some Oscar attendees tend to play it safe with their gowns at the Academy Awards, but these guests brought a bit more skin to the red carpet to make for a completely jaw-dropping Oscar fashion moment. Here's a roundup of the 55 sexiest dresses—featuring mesh, cutouts. leg-slits, and more—that appeared at the star-studded ceremony over the years.

Going backless in 1957? No big deal for Vikki, here. This sexy twist on a classic LBD is absolutely everything.

A little plunge never hurt nobody. Here, she stunned in a sequin halter neck gown with a tiara and opera-length gloves. Casual.

Look back at it! The stylish shawl completed this all-white halter column.

Yes to this cleave moment. Elke Sommer sported a sexy sequined gown, fur coat and white gloves, giving off major, "I'm more glam than you" vibes.

You can't go wrong with deep V's and sparkly embellishments. Diahann Carroll wowed in this sequined dress, complete with a chic 'do and flawless smokey eye.

Barb put a Peter Pan collar shirt and sparkly flares on the map when she donned this sheer getup to the '69 Oscars.

Diamonds and décolletage go together like peanut butter and jelly. We'd be smiling too if we rocked this periwinkle hue as well as Liz.

Plunging blue wrap dress, FTW. Fun fact: The actress took off the top half to reveal a spaghetti strap version of this look on the Oscar's stage. A true icon.

Okay, Cher. We see you in this crop-top, ultra sheer two-piece look. Just look at those abs!

Raquel at it again in a plunging halter number. Adding a wrap necklace and pendant earrings gave this look a classy touch.

The ultra-plunging neckline was obviously a major Oscars trend in the '70s. Lauren Hutton made sure to channel her inner Greek goddess at the ceremony with this white, flowy gown.

Oooooh! A mini!! Here, the icon sparkled in a gold metallic number behind the scenes.

If you thought all these other plunging necklines were low, Cher's is all the way down to her bellybutton! She arrived in this see-through gown and accessorized with statement earrings.

More cutouts! Jennifer O'Neill stole the show on the red carpet with this daring gown and beaded headpiece.

This strappy criss-cross back made a definite red-carpet statement. Here, she accessorized her curly updo with a chunky, gold headband. Talk about being ahead of the trends!

Plunging + strapless = one sexy Oscars moment. Sonia Braga looked gorgeous in this sequined gown complete with floral-patterned pearls and earrings.

Cher does not come to play when it comes to dramatic looks at the Academy Awards, if you couldn't tell. This Bob Mackie design is iconic to this day, and it looked even better with her Best Actress Oscar for Moonstruck.

More extreme plunge action, courtesy of Versace. This fiery-red design looked gorgeous on Cindy Crawford, but then again, doesn't everything?

And next up, the supermodel wore a bustier and bandage dress all wrapped into one. Cindy stunned yet again with an all-white look and diamonds (naturally).

She looked beautiful in this sparkly, halter gown and tousled hair. This is one timeless style, IMO.

Taking backless to new extremes. Marisa Tomei looked like a true '90s icon in this flowy dress, bangle on her wrist, and pixie cut.

What free the nipple looked like in the early '90s. *Takes notes on how to pull off this look myself.*

Here, the British actress lived that low-cut, sweetheart neckline, and spaghetti strap life. It's like looking at a shining star in human form, wow.

A little side-boob for ya! No major accessories were even needed for Gwyneth's gorgeous baby pink dress. Simplicity is key.

Crop-toppin' all over that red carpet. Here, the actress (and now Red Table Talk host) sported an extra-shiny set showing off her toned abs. All we can say is: Bring back two-pieces to the Oscars!

A little cleave goes a long way. Leave it to J Lo to channel sexy 1940's pinup vibes in this pretty embellished gown.

Nicole Kidman definitely stood out in this chartreuse satin gown paired with statement earrings. Oh, and Tom Cruise was also there.

More slit action. The white dress with a draped neckline looked even more gorgeous with a coordinating floral hairpiece and pointy pumps.

I stan a backless illusion embroidery situation complete with a little hummingbird. 10/10, would wear.

When in doubt, wear your blazer backwards and wow the world. This is prob one of Celine's most iconic looks, and she's worn a LOT of over-the-top outfits.

Lucy Liu gave everyone a run for their money with the sexy sheer panelling on this illusion dress. So mesmerizing!

Look, *another* low neckline! The belted waist and intense diamond necklace made quite the fashion statement.

That's a lotta back! The butt ruching combined with the orange hue made this one eye-catching ensemble.

Three words: Totally. Sheer. Top. Halle Berry looked like she combined two dresses into one with this Elie Saab satin number, and it's one of her most recognizable red-carpet looks of all time. She won the Oscar this year for her performance in Monster's Ball.

Another Oscars red carpet, another plunging, backless halter look, this time with Angelina's silky dress with a matching shawl.

Now, this is a backless dress! Hilary Swank dropped jaws in this navy Guy Laroche gown and won the Best Actress Oscar for Million Dollar Baby that same night.

More plunges, less problems. This orange dress with its embellishments on the waist combined with her tousled hair gave this that effortlessly sexy vibe.

Here's a lil more side boob for you. Camila Alves made quite the red-carpet arrival in this all-black gown and slicked-back bun.

JLaw's fire-engine red Calvin Klein dress heated up the Oscars that year. She was nominated for her breakout performance in Winter's Bone.

Sheer stripes, shoulder cutouts, and a major low back made this dress a knockout at the 2012 ceremony.

Ah, yes the meme seen 'round the world. Angie donned this strapless black dress with its thigh-high slit to the awards this year, and wanted to make sure EVERYONE noticed.

The actress and singer wore a striking, figure-hugging blue gown with sequins and sheer lace, complete with a thigh-high slit. She performed the goosebump-inducing Dreamgirls hit "And I Am Telling You I'm Not Going" on stage later that night.

Slits, sheer fabric, and a dramatic plunging neckline = the recipe for a sexy Academy Awards 'fit.

Margot channeled old-Hollywood glam in a sheer-sleeved gown with a red lip. But the real stunner here was that huge antique Van Cleef & Arpels necklace. Wowza.

Love a leather bondage situation on the red carpet. Kerry Washington decided to go for an edgy look with contrasting colors to the 2016 Oscars.

*Insert red-hot joke here.* Charlize Theron completed her bold outfit with a simple drop necklace that accentuated the neckline. So sparkly!

This Calvin Klein dress has it all: A strappy back, side-boob action, and a deep neckline. She was nominated for her performance in Brooklyn this year.

Nothing to see here, just a gown with a completely sheer bodice. We're also HERE for Chrissy's statement shoulders and revealing leg slit.

This dress was basically just a skirt with a front flap and back flap. Combine it with side-boob and it makes one heck of a sexy Oscar moment.

Totally sheer? Totally cool. Violetta Komyshan quite literally bared all (she joked about her see-through dress later on Insta), in a tight-fitting black column.

Another strappy back for ya! Eiza Gonzalez's bright yellow gown gave off major happy vibes at the 2018 Oscars.

Taraji looked like a goddess in a transparent gown. She was donned a flowy Vera Wang number with cutout details.

Brie Larson shined brighter than my future, tbh, in this slinky chainmail dress, and I'm totally okay with that.

You know we LOVE a good sheer look. Amandla Stenberg straight-up glowed in this silver fringed column.

The actress wore a fitted strapless gown with a dramatic train and thigh-high slit to the 2019 awards. She went on to win the Oscar for Best Supporting Actress for her emotional If Beale Street Could Talk performance.
