From the pattern:
“One of the newest models in sports garments… This one is knit in teazle yarn and is very handsome in Joffre blue with collar and ornamental rings crocheted in yellow silk. Three crocheted buttons fasten the vest in front. A crocheted cord of the blue is run through the rings at back and fastens around the waist under the coat. The vest is knit from neck down, with no seams except at the shoulder.”

No yarn, gauge, or measurements are given.
