Remember the glow-in-the-dark fairy dress at the Met Gala? In 2016, the red carpet show of the Met Gala at the Metropolitan Museum of Art, New York, this year's theme was "Manus x Machina: Fashion in an Age of Technology". Many girl stars are wearing skirts with a technological style. Although there are a variety of styles, they all lose to actress Claire Danes when it comes to fitting the theme. At that time, Claire Danes wore a glow-in-the-dark dress, which was a blockbuster in the fashion industry, making celebrities flock to it. This dress looks unremarkable and seems to have nothing to do with technology. But once it's in the dark, the dress's peculiarity emerges: sparkling in the dark, it couldn't be more beautiful! The dress, designed by Zac Posen, has 30 mini battery packs on the bottom of the dress. Because the lining fabric of the beautiful skirt is made of optical fiber material, it glows with attractive fluorescent colors when it is in the dark. The design features of Zac Posen can be summed up as follows: the use of wrinkled satin, the fishtail-shaped skirt, the bias cutting technique, 3D printing and other high-tech technologies, each of which is an amazing art treasure.
