The title is “Boy Doll’s Vest” in the Needlework & Crafts magazine. It is “Sleeveless Cardigan” in the Doll Fashions magazine.

Yarn: 1/2 ounce

Additional materials: six small buttons (The Needlework & Crafts instructions only call for five buttons in the materials, but that’s presumably a misprint since both sources tell you to work six buttonholes.)

This vest is made in pieces and seamed. There is a crocheted edging around the armholes.

Sized for a Ken-type doll with the 1960s figure :
6.25”/ 4.5”/ 5.125”. The fit may vary on modern dolls.
