With so many iconic red carpet moments to his name, Christian Siriano could literally write the book on celebrity dressing.

And with the release of his new anthology, “Christian Siriano: The New Red Carpet,” he’s done just that — all while spilling plenty of previously untold stories from his time as a fashion visionary.

“It’s called ‘The New Red Carpet’ because this is what I think the new world on the red carpet should look like,” he told Page Six Style at his star-studded launch party on Thursday night.

Christian Siriano says it’s ‘frustrating’ that ‘Housewives’ don’t pay for his clothes: ‘We’re not an endless closet’

“It should look like all these different types of people … [whoever] you are, you should be celebrated on the red carpet,” he added.

“I hope the younger generation sees it as like, ‘Wow, this is what I hope to become one day.'”

Several stars are on the same (literal) page when it comes to that vision, as Laverne Cox, Laura Linney, Rosie Perez and Coco Rocha — all of whom feature in the new book — partied at Soho’s The Mulberry to celebrate the release.

Cox even matched her shimmering gold coat to the cover of the Rizzoli-published tome, striking several poses for photos with the man of the hour.

While readers will have to pick up a copy to get all the behind-the-scenes details, Siriano gave us a hint about the contents of his go-to styling kit, saying he carries a needle and black and white thread “everywhere” he goes.

“I’ve had so many times [where] a zipper breaks or something’s messed up,” he explained. “That’s my thing. I’d rather sew it on them, right then and there. I’ve done that! You never know.”

And while the “Project Runway” alum’s the common thread connecting the who’s who of Hollywood, he was hesitant to name a favorite look from his book, which is sorted from A to Z (Alexa Chung to Zendaya, of course).

“It’s such a good mix — from the first time I ever dressed Cardi to the first time I dressed Ariana Grande,” he tells us.

“They all have their own stories, and I think that’s what was kind of fun about it.”
