I had baby socks knitted with Marie Cotton Silk yarn! The feel is so soft that I wanted adult-sized Marie socks too~~. If you turn them inside out, the seams will be on the outside, and the soft Marie yarn pile will be on the inside. Although they are not two-toned, like organic cotton baby pile socks, they are also cute when worn with the inside pile and the cuff folded down a little♪ They are easy to wear and don't slip off, but they have a relaxed pile knit. Visually, they look like they are the perfect size for newborns, but they stretch generously, so they are perfectly fine for babies around 1 year old. Therefore, I think you can wear them for a long time.
