I started hissing to DD during this movie! "Look at that sweater! Where's my pen! I need to take notes!"
DD started hissing: "Shut up, Mom! It'll come out on video!"
It's a turtleneck with raglan sleeves. Deceptively simple. I'm pretty sure that stitch pattern is "honeycomb". It's probably not done in the round, but you could. Is that k2, p2 ribbing? Somebody else chime in here!
I think you could copy this pretty easily. I haven't seen a pattern for it. Good luck!
