I have multiple pairs of these cashmere socks and bought them out of season as they were on sale. They hold up well but they do shrink if you dry them.

So soft & warm - I have 3 pairs

This is one of the best J Crew purchases I've ever made. It feels like your feet are wrapped in clouds, and the material is thin and warm. I'll definitely be getting multiple colors and gifting them too. I hope they keep making these forever.
