Butts Out, Nipples InRihanna Flashes Nipples in Sheer Dress — and 8 Other Stars Taking the Trend by Storm

Melissa George: The I'm Attending a Vogue Party and Need to Wear Something Controversial

The 38-year-old actress definitely got some MAJOR attention at the CFDA/Vogue Fashion Fund Awards in NYC on Nov. 3 in this totally-sheer-up-top number. Not to mention, the temperature was in the 40s.

VERDICT: This is clearly a ploy for attention. It's hard to stand out at an event like this, but wasn't the deep V-neck daring enough?!

Lady Gaga: The I’m Lady Gaga, What’s Your Excuse?!

Lady Gaga stepped out in this “shirt” (we say it with quotes because not only is it sheer, but it also splits open riiiight at the chest to put her bra on display) and a sheer bra underneath.

Impressively, as far as Mother Monster’s sartorial choices are concerned, this is one of her more tame and “conventional” fashion looks!

VERDICT: We’ll allow it. Partially because Lady Gaga has been flashing her nipples longer than some other stars have been alive (we’re lookin’ at you, Kendall Jenner!), and partially because her adorable French Bulldog puppy Asia is giving us the puppy dog eyes…

Rihanna: The Naked Dress, But it Works Because She’s Hot…and She’s Rihanna

Listen, nipples on a red carpet are always very surprising, but when it's RiRi doing the bra-less dance, we can't say we're that shocked. Come on, people. Her Instagram — hello?!

The songstress attended the 2014 CFDA fashion awards in NYC on June 2 to accept the Fashion Icon award. And, you know, to turn some heads in a custom Adam Selman sheer gown that was encrusted with over 215,000 Swarovski crystals. She sported a Commando thong underneath.

RULING: Proof that exposed nipples can look classy. #SomethingWeThoughtWeWouldNeverSay

Scout Willis: The Desperate to Be Noticed Sheer Top

Hmm…how else would the 22-year-old daughter of Bruce Willis and Demi Moore get press aside from the fact she's the daughter of Bruce Willis and Demi Moore? Yeah. Exactly.

Unfortunately, the world was subjected to seeing this when she showed up to an event in LA in early May. Clearly she wanted to upstage her sister Rumer's visible pink panties. Our eyes will never be the same.

RULING: NO. JUST NO. AWFUL. STOP IT. MOVING ON.

Madonna: The I’m 55 and Can Still Show Off My Lovely Lady Lumps

Here's the Queen of Pop on all fours in a BDSM-inspired getup. High-waisted bottoms with fishnet stockings, leather gloves and a harness bra providing absolutely no coverage complete her look for the May/June 2014 issue of L'Uomo Vogue.

Considering she's been in many compromising positions before, the shoot isn't the most shocking for the songstress. Let's just hope she doesn't keep an issue around the house for her kids to see.

RULING: Whatever. She's Madonna and doesn't really care what anyone thinks. OBVIOUSLY.

Sharon Stone: Whoops I Forgot a Bra Before Heading to Dinner (But I Totally Planned it That Way)

Kudos to the actress for looking pretty freakin' phenomenal at 56. But the outfit she wore in March could have looked just as sexy with some support underneath.

RULING: You'll always be a sex symbol, Sharon. No need to keep proving it. Put a bra on and keep it moving.

Kendall Jenner: The I’m 18 Now So I’m Showing Off These Nips Every Chance I Get

OK. We get it. She's a high-fashion model and yada yada yada. When Kim Kardashian's little sister took part in Marc Jacobs' New York Fashion Week runway show in February, some critics bashed the teen for exposing her breasts in a see-through top and others embraced it because she's a model and some models have no problem letting the world see 'em in the flesh.

RULING: She wasn't the only leggy lady with the goods on display, so she gets a pass — even though she obviously did this for attention. Hey, she only learned from the best ::cough:: Kris Jenner and Kim ::cough::

Rosie Huntington-Whiteley: The One Nipple and One Nipple Only

The summer issue of V magazine featured the supermodel flashing her nipple. People have done worse…

RULING: It's a classy nipple in our opinion.

Kim Kardashian: The This is More Clothes Than I’ve Worn in the Past, So Deal With It

There's no chance we'd devote a gallery to nipples without featuring the one and only Kim! Just days before she tied the knot in Italy in May, the brunette bombshell went bra-less in a peach-colored top — and seemed a bit cold as she walked around the streets in Paris with Yeezy.

RULING: At least she's wearing more clothes than Kendall.

Beyoncé: The Tease

Unlike the ladies before her, Queen Bey keeps the gals covered up in a swimsuit — but still decided to share this photo with her fans this week even though her nipples are poking through.

RULING: Hey, that necklace is pretty fierce. We mean…that's what she really wants us to be looking at, right? Riiight.

Simon Cowell: The P-R-O

Because how could we not end this with the man who puts every pair of nipples to shame every single time he steps out?

You go, boy.
