Equivalent of the Oscar’s red carpet, the Met Gala brings together an invite-only list of dressed-up celebs, bigwigs and this year-- tech. The theme of the gala, which benefits the Metropolitan Museum of Art's Costume Institute, was “Manus x Machina, Fashion in an Age of Technology.”

It was a start-studded, LED night that bought style and tech together in haute couture-level drama with Silicon Valley-level uniforms (the event was co-hosted by Apple's chief design officer, Jonathan Ive). From robotic arms to Tomaguchis to dresses made entirely of recycled plastic bottles, "tech" meant slapping on metallics, with everyone from Kim Kardashian to Lady Gaga to Taylor Swift shimmering in bright, futuristic ensembles. The red carpet proves just how extravagantly fashion and tech can come together. 

Maybe the next dress you buy will have  a power button. For now, fashion’s innovations are mostly happening behind the seams. Click ahead to see the looks.

1) Karolina Kurkova

Model Karolina Kurkova was wearing a dress designed by Marchesa and IBM's Watson team. The "cognitive dress" was covered in LED lights that changed colors based on what people tweeted about the two brands throughout the night, according to Wired.

2) Claire Daines

Claire Daines wore a Zac Posen dress that appeared at first as a simple, classic white gown -- the likes of which Grace Kelly might have worn 60 years ago -- but was actually filled with fiber optics that illuminated it in a multitude of shades.

3) Allison Williams

Actress Williams' gown was adorned with 3D-printed white flowers, designed by Peter Pilotto.

4) Emma Watson

Watson went eco-friendly with an outfit made from recycled materials aka garbage-- literally. The off-the-shoulder look, designed by Calvin Klein, was made from recycled plastic bottles for a project that the designer, along with the consulting firm Eco-Age, called the Green Carpet Challenge, reported the Telegraph.
