It looks like Halloween got an early start this season with lots of boo-bies.

On Saturday (Sept. 22), models took to the runway during Milan Fashion Week to show off the 2019 spring collection by designer Giuliano Calza, and onlookers had to do a triple take at the three-breasted models—no, seriously.

See for yourself the odd sight that had social media utterly confused.

So what’s with the Italian label’s choice to outfit their models with a third prosthetic breast to sport their neon bralettes? 

According to an interview with WWD, Calza said it was a wake-up call. 

“We’re a young group here — we’re all under 30 — and I wanted to talk to people our age about the future and get them thinking about plastics, water shortage, and the environment,” he shared. “Full sustainability is impossible, and I wanted this show to be a wake-up call.”

Although strange, it does make you think.
