These are by far the cutest socks I've ever owned! I can't believe how adorable they are. These are a lighweight, thin sock, but very stretchy. Perfect weight for warmer weather. Or wear them at work with your dress shoes to give yourself a smile throughout the day, when you peek at them when no one is looking. The listing says they'll fit women's shoe sizes 6 - 10, and that seems pretty accurate. I wear a 9 and they just fit me, but pretty much stretched as far as they can. I'm very happy with them, as a cat lover, I'd say I'm actually tickled pink!
