The Victoria's Secret Fashion Show taping is only a week away, and Jasmine Tookes is practicing her strut in a behind-the-scenes video from her Fantasy Bra fitting. 

The 25-year-old Angel has been chosen to model the $3 million Bright Night Fantasy Bra designed by Eddie Borgo at the brand's highly-anticipated show, which is being held in Paris this year for the first time.  

The new clip shared on the Victoria's Secret YouTube sees the Angels trying on their risque costumes, and Jasmine gets plenty of oohs and aahs as she steps out of the dressing room wearing the showstopping bra that features nearly 9,000 precious gemstones.

Look at it shine! Jasmine Tookes showed off the $3 million Bright Night Fantasy Bra in a new behind-the-scenes video from the Victoria's Secret Fashion Show fittings

Wow! Designed by Eddie Borgo, the bra has 9,000 precious gemstones and weighs about 450 carats

Jaw-dropper! Jasmine, 25, admired the glitz and glam in the mirror after being totally outfitted in the ensemble

Bringing her A-game: The Angel said she has an 'alter-ego', because she is normally 'quiet' but turns up the drama on the runway

It's undoubtedly an honor to be chosen to wear the diamond-and-emerald bra that weighs nearly 450 carats, and Jasmine happily reveals her trick for commanding the runway.

'I have, like, a little alter-ego, because I am normally very quiet and laid-back, but when I get on the runway, I just want to try to be very powerful and really give it my all,' she admits as she is seen shimmying in the tasseled, heavily-beaded ensemble.

The footage sees many of the brand's beloved stars posing and walking in their elaborate costumes ahead of the show, and Victoria's Secret executive producer Monica Mitros explains that they started doing fittings right after they knew who was going to be walking the runway for the brand.  

'It's one thing to make the outfit and make it on the fit model, but when it gets on the model who is wearing it, that's when it really comes to life,' she says. 

Full-on glamour: Josephine Skriver could also be seen modeling glitzy lingerie with a Swarovski crystal cape

Lots of man hours: When the original cape wasn't silver enough, eight people spent four days rebeading it

What a dream! Josephine seemed thrilled to show off the glistening number

Gorgeous: Adriana Lima, a 16-year Victoria's Secret veteran, also appeared in the video

Total pro: She exclaimed over her killer outfit and will be opening one section of the show

In addition to Jasmine's $3 million bra, another glittering ensemble set to appear in the show features a bedazzled Swarovski crystal cape that will be worn by Josephine Skriver.

'The first time we saw the Swarovski piece on Josephine was totally magical,' recalls Sophia Neophitou, the collection creative director. 

However, it took more than one try to get the dazzling creation just right. 

'It came and the strands were more white than silver, so there has been eight people rebeading the sleeves for four days to make it work the way I want to see it on Josephine,' Sophia explains. 'It takes a village. It really does take a whole team of people.'  

Ooh-la-la! Lily Aldridge was in the video as well, adding a pair of feathery wings to her lingerie

While the models posed on-screen, Victoria's Secret executive producer Monica Mitros explained what the fitting process is like

Superstar! Alessandra Ambrosio, another 16-year veteran, flashed on camera as well

Woohoo! Taylor Hill, who made a splash at the most recent New York Fashion Week, was thrilled to learn she'd be opening a section of the show

Supermodel status: She could be seen in a relatively demure black dress and lots of jewelry

Josephine seems more than pleased with the creation, and she has no problem working the long beaded sleeves of the cape as she practices her runway walk. 

The video also includes the heartwarming moments that some of the models learned that they would be opening or closing certain sections of the show. Many are also seen exclaiming over the beauty of the pieces they get to wear.

Adriana Lima, who is no stranger to the runway, will be opening one section in a red lace push-up bra and blue bondage-inspired lace underwear, along with thigh-high patent boots.

'I'm so happy,' the 35-year-old, who will be walking in her sixteenth show, says in the video. 'I mean, this is amazing,' she adds, gesturing to her outfit.

Bringing the heat: Sara Sampaio sizzled in a black bra, panties, and a super-sexy garter

Big moment: She seemed in shock to be getting some good news on set

Alessandra Ambrosio, Lily Aldridge, Sara Sampaio, Stella Maxwell, Martha Hunt, Elsa Hosk, and Taylor Hill also appear in the video, flaunting glamorous crystal-covered bodysuits, skimpy lacy bralets with dramatic feathered wings, and vampy garters.

In addition to trying on the pieces, they practice their walks, pose for promotional shots, and — can we blame them — admire themselves in the mirror.

'It really is amazing to look around the room and see all the wings and all the outfits because so much work went into them,' says Monica, the executive producer. 'And to see the artists and look at it, and to see their sketch and their dream realized, it's fun and it's exciting.' 

Time to practice: Elsa Hosk could also be seen strutting her stuff and posing

Work it! Lais Ribeiro made a colorful statement in her Asian-inspired outfit

Stay tuned for the fun! The ladies will film the show in Paris next week, and it will air on CBS on December 5

She also stressed the importance of the fittings, which ensure that every bit of fabric is perfectly tailored to these perfect bodies. 

'These days of trying on the wings and trying on the outfits are really the most crucial days that we have leading up to the show,' she says.

While the show will film on November 30, it's set to air on CBS on December 5, with Lady Gaga, Bruno Mars, and The Weeknd scheduled to perform.
