Don't you just love Halloween? It's kind of like the Met Gala in that it's one of the few occasions every year when celebs go all-out with supremely extra dress-up looks. And, when it comes to costume ideas, A-listers take their inspo from all kinds of places: trending TV shows, iconic horror movies, and, in Hailey Bieber's case, the catwalk.

This weekend, the beauty mogul and high fashion model took part in the spooky szn festivities with a killer homage to one of the most iconic runway moments of all time. The 25-year-old shared snaps of her heavenly costume - a bra and underwear set comprised of *stunning* pink roses, a matching flower crown, and a floaty pink train. The look in question is a tribute to Yves Saint Laurent's famous spring/summer 1999 haute couture show, featuring Laetitia Casta wearing a practically identical look.

Hailey teamed the 'fit with super rosey blush (approps) and her hair worn down in fairy-like waves. "Happy Halloweekend πŸ‘» inspo: YSL haute couture 1999 πŸ’" she captioned the pics on Instagram.

And here's the OG look from 1999:
