16 Times Celebs Wore Seemingly "Inappropriate" Wedding Guest Outfits (And If The Bride Or Groom Approved)

In 2023, Olivia Wilde wore a white "wedding dress" to her friends Colton Underwood and Jordan C. Brown's wedding "just so [she] could make a joke about it in [her] toast."

Traditionally, Western weddings come with certain unspoken dress code for guests, like not wearing white or red. Of course, some couples don't mind if their guests break these rules, and a few may even encourage it, but for the most part, the main rule is this: don't take away attention from the couple who are getting married.

Here are 16 celebs who were called out for wearing seemingly inappropriate outfits to another person's wedding:

1. Lana Del Rey wore a white LoveShackFancy dress with pink flowers on it to Jack Antonoff And Margaret Qualley's 2023 wedding.

Her look sparked an online debate about if it's ever okay to wear white to a wedding that isn't yours.

2. In 2023, Hailey Bieber wore a Fancì Club dress that was so light blue that it photographed white to Stephanie Shepherd and Larry Jackson's wedding.

In her Instagram comments, fans questioned her decision to wear the dress:

you look silly wearing white to a wedding
why wearing a white dress to a wedding though

3. Attending the same wedding, Kim Kardashian wore an Alaïa dress that showed her underwear.

She was called out for "nearly upstaging" the bride.

4. Kim's look was compared to the Monot outfit her sister Kendall Jenner wore to her friend Lauren Perez's wedding reception in 2021.

Her dress was widely criticized and called "blatantly disrespectful to the bride." However, sharing pictures from her wedding on Instagram a few months later, Lauren commented, "[KENDALL] LOOKED STUNNING AND I LOVED IT!"

Kendall herself replied, "Obvi asked for your approval in advance too. We love a beach wedding."

5. The same day Kendall wore her controversial dress, Kim was called out over her look at Paris Hilton and Carter Reum's wedding.

While many commenters praised her look, others gave criticism similar to what Kendall received.

6. When Dua Lipa attended Olive Uniacke and Dane Ensley's wedding in 2022, she wore a lacey, lingerie-inspired Bottega Veneta slip dress.

Some fans called her out for wearing a dress that photographed almost white or for trying to "steal" the show. However, it's worth noting that the bride wore a hot pink wedding dress.

7. A few weeks later, Dua Lipa wore a sheer white Mugler dress to Simon Porte Jacquemus and Marco Maestri's wedding.

In context, the seemingly controversial outfit choice made sense, as it was designed by Simon himself. Other guests, including Mica Argañaraz and Didi Stone, also wore white.

9. In 2021, Olivia Palermo wore a white Giambattista Valli dress to Simon Huck and Phil Riportella's wedding.

Most commenters praised her look, but some debated whether it was okay to wear white to a wedding, even if there was no bride:

not a dress for wedding's friend
soo you can wear off-white floral to a wedding as it's a gay weeding? what happened to basic etiquette?

10. Cheryl Cole wore a white Zuhair Murad dress with sheer panels and lots of feathers to Nigel Hall and Philip Bates's 2018 wedding.

Some felt the look was "too bold" or too white for a wedding guest. Responding to criticism on Instagram, she reportedly wrote, "Them: How could you wear such a thing to a wedding? I bet the bride was upset. 😡 Me: There wasn't one. 👬"

11. Cara Delevingne wore an Emporio Armani tuxedo to Princess Eugenie and Jack Brooksbank's 2018 wedding. The ceremony's strict, traditional royal dress code called for women to wear day dresses with hats and for men to wear morning coats.

However, Cara had the bride's permission to break the dress code. She told Grazia, "Eugenie has been a friend of mine since I was a kid, and I've always wanted to wear tails. I texted her, as I wasn't sure about it, and she was like, 'Of course, I expected nothing else from you!'"

12. After Candace Cameron Bure posted a picture of her family dressed for a wedding in 2021, she and her daughter were criticized for wearing red, and her husband and son were called out for not wearing socks.

In response to a comment about the red dresses, Candace said, "Anything goes in L.A. There were 4 women wearing red dresses to the wedding." Then, replying to a commenter who called the guys' lack of socks "very unattractive," she said, "Comments like this are unattractive. People enjoy style in different ways. It's not always necessary to share your opinion."

13. At her Game of Thrones costars Rose Leslie and Kit Harington's 2018 wedding, Sophie Turner wore a red tuxedo jacket dress and thigh-high boots.

The creative ensemble was praised by some and reviled by others. Sophie herself regretted the look, later telling Elle, "One of my worst looks...I had a fashion emergency. It was either the thigh-high boots or these nice heels, but I felt like if I just wore the heels all of my leg is showing, if I cover up a little bit then... urgh, it was a disaster. Worst fashion choice."

14. When her The Real Housewives of Atlanta costar Porsha Williams married Simon Guobadia in 2022, NeNe Leakes wore a see-through dress.

16. And finally, when her brother Frankie Grande married Hale Leon in 2022, Ariana Grande wore a custom Vera Wang outfit.

Some Instagram commenters thought her look wasn't a wedding-appropriate.

However, Frankie gave his approval.
