Mariah Carey says being "freezing" made the making of her iconic All I Want for Christmas video brutal

She said: "I was so freezing (in my Santa suit.)

"It was definitely not chic and effortless."

Despite her discomfort, Mariah revealed she has a fond attachment to the outfit.

She added: "Someone asked me, 'Do you still have that one?' and I'm like, 'yeah, I use the same one every year'."

Mariah's festive favourite is part of her 1994 Merry Christmas album and has become a global holiday staple, earning three Guinness World Records titles, including the highest-charting holiday (Christmas/New Year) song on the Billboard Hot 100 in 2019 alone.

Mariah also recounted how the track originated in a modest setting.

She said: "I started writing that on a little DX7 or Casio keyboard that was in this little room in the house that I lived in at the time in Upstate New York lifetimes ago.

"Just writing down everything that I thought about. All the things that reminded me of Christmas that made me feel festive that I wanted other people to feel."

The singer has returned to her festive persona repeatedly.

For the 20th anniversary of All I Want for Christmas Is You, she released an updated music video featuring her twins, Moroccan and Monroe, both 15, dressed in holiday outfits.

Mariah has also reprised her Santa-inspired ensemble alongside a plunging red gown and a costume influenced by The Nutcracker.

Her Christmas influence extended to Mattel, which in 2023 created a Barbie in her likeness, inspired by her holiday style.

Mariah told People about her toy: "When I saw my doll, I was like, 'Oh my gosh, this is so cute.' Because it's based on the Christmas dress that I wear in the second All I Want for Christmas Is You video, which was directed by Joseph Kahn."
