My daughter was born 7 weeks early and I was struggling to find cute socks for her. I was hesitant to buy these socks as nothing seemed to fit her, but I decided to give it a try and I'm so glad I did. They fit her perfectly and she can finally wear some of her bubble outfits. They look like nylon and look more like stockings than socks. I wish they were warmer, but for me it's not critical. I will be buying more in additional colors.
