Taylor Swift is giving a peek behind the curtain.

The singer celebrated the success of her latest single, “Opalite,” with a slideshow of behind-the-scenes photos and videos from the song’s music video and production, including rare makeup-free moments.

“Just a few Opalite memories to celebrate,” wrote Swift, adding, “I can’t even sum up my excitement and I’m so blown away by the love you’ve shown this song and video.”

In the first clip of Swift sings the lyrics “You had to make your own sunshine,” wearing her hair naturally curly with an oversized green sweater from The Row ($4,860 $1,458) and no glam to speak of.

She added some bling with a rose gold rose-shaped ring by Piaget ($2,580).

In another studio session, she goes makeup-free, this time wearing a darker green sweater and a gold necklace with a vintage heart charm.

The 36-year-old is rarely seen without full glam — her signature red lip, a smokey eye and typically straight hair.

Elsewhere in the post, she also stands tall against the tinsel-covered set in an understated black turtleneck and dark gray trousers and shows off one of her costumes: a 1990’s-era mom jean, striped turtleneck and denim vest combination.

“Never in my life have I felt so myself,” she joked in a selfie video of the brunette look. “This is actually who I was meant to be.”

And she added a final toast, clad in Ralph Lauren’s Olympics-edition American flag sweater, toasting the project with Orrefors Devil champagne flutes ($350).

Though her navy version has long since sold out, the summer-ready white version of the American sweater is still in stock at Ralph Lauren ($398).

Swift also took time to call out that her latest success, a Hot 100 #1 placement for the song off of her latest album, “The Life of a Showgirl.”

“To put this into perspective… This is actually the first time I’ve had two Hot 100 #1s off of one album since my album 1989 came out in 2014, nearly twelve years ago!” she wrote.

“It all adds up to me being so thankful to the fans who helped make this happen by welcoming this song into your lives with open arms.”
