Rainbows have been rocking the refraction game here on Earth (the only planet known to have them) ever since liquid water showed up here 4.4 billions years ago. Yet somehow, rainbows on clothes only got really cool in the 1970s. Get retro in a pair of these rad rainbow socks with little 'bows on a black background. Fits women's shoe sizes 6 to 10. 51% cotton, 47% polyester, 2% spandex. Made in Korea.
