Striking vintage cobalt blue sweater

Ribbed sweater made of dense and squishy yarn. No fabric content tag available but feels like a soft wool, or perhaps a wool blend. It’s not itchy. Boxy retro cut with cropped raglan sleeves. (Shape is reminiscent of a Babaa no. 18 sweater. Babaa stock photos for reference) Approx measurements Pit to pit - 22” Body length - 22” Pit to cuff - 15”
