Four-time Olympic gold medal-winning gymnast Simone Biles wore a three-in-one, night sky-inspired dress weighing over 40 kg at the Met Gala 2021. The dress consisted of a hand-embellished skirt covered in Swarovski crystals. More than 100 people worked for 6,650 hours to make the dress. "I personally don't think anybody's dress is gonna be better than mine," the 24-year-old said.
