But that's what happened Sunday when comedian and actress Tiffany Haddish strode on stage in a $4,000 white Alexander McQueen dress she's worn publicly at least two other times, widely considered a faux pas in Hollywood.
Haddish wore the dress at the premiere of "Girls Trip" in July. She wore it again during her stint as host of "Saturday Night Live" in November - and dedicated half her opening monologue to it.
"My whole team told me, 'Tiffany, you cannot wear that dress on 'SNL,' you already wore it. It's taboo to wear it twice," Haddish said on "Saturday Night Live."
"I said, 'I don't give a dang about no taboo, I spent a lot of money on this dress,'" Haddish said. "This dress cost way more than my mortgage."
She then went on to detail where else she would wear the dress: at a bat mitzvah, at her own wedding, and even at her own funeral one day.
"If I die and even if I become fat as hell - if I'm the biggest, fattest - I don't care," she said. "When I'm laying in that casket, guess what's going to be laying on top of my fat-ass body? This dress."
She'd apparently wear it to the Oscars, too.
Not only that, she walked out on stage wearing slippers and carrying her gold high heels, as did her co-presenter, Maya Rudolph.
"We are so happy to be here but our feet hurt," Haddish said.
Earlier in the evening, Haddish walked the red carpet in a much different outfit, a traditional Eritrean dress, wrap and headpiece dedicated to her father, who died last year.
"He said one day I would end up here and if I ever end up at the Oscars to honor my people, so I'm honoring my fellow Eritreans," she told ABC.
The 38-year-old Haddish, who became a breakout star after stealing the show in "Girls Trip," has spoken often about her upbringing, which included time in foster care and getting into trouble in school.
Her continued authenticity despite her growing celebrity has helped her stand out in Hollywood.
She joked to The Associated Press in July that her bank account "don't show movie star yet."
"That's the part I'm waiting on," she said. "When do that happen? They say like nine months. It's like a baby. I'm waiting for the delivery."
