On October 31, the model GIgi Hadid revealed her real costume when she arrived at Heidi Klum's Halloween party in New York.

Early on, Hadid was spotted wearing a pair of green fuzzy ears, that apparently was just a tease.

Wearing a Sandy costume from the ultra-famous musical Grease, the 20-year-old went old school! Starring John Travolta and Olivia Newton-John, Grease came out in 1978.

Monica Rose, the Kardashians' go-to stylist, was the one ressponsible for putting together, Gigi's flawless ensemble and she pulled it off with ease.

From American Apparel, she wore nylon high-waisted spandex, while from House of CB, she had on a crop top with a sheer panel, and from Caroline Blomst  a lace-up leather jacket. Even while standing next to Heidi Klum or Jessica Rabbit herself, the supermodel no doubt, had all eyes on her.

She clearly couldn't help adding just a dash more of sex appeal by glowing more skin than the original ensemble worn by Olivia in the classic film. She actually did channel the original character while assembling her outfit. 

Gigi sported a pair of red sandal heels just like Olivia did, and some very tight, shiny spandex leggings, which worked just like the originals. It totally showed off the Victoria Secret model's lengthy gams.

The dancer, Julianne Hough is taking on the role of Sandy for the Fox special, Grease: Live, but until then, Gigi from head to toe was perfect, posing like Sandy on the red carpet at Lavo in New York.

We wouldn’t be surprised if she said, “Tell me about it, Stud” to reporters!

Gigi had a reason to celebrate late, since she revealed she was cast in this year's Victoria Secret Fashion Show.

While she has appeared in Victoria's Secret Pink, the model failed to get cast in last year's lingerie show.

Since her disappointment in 2014, Gigi has made a name for herself by modelling for brands such as Balmain and appearing on the runway at Paris Fashion Week.
