Pattern is Japanese but fully charted using standard knitting symbols. Photo and pattern link at the very bottom of page, leftmost photo. (Direct link to pattern PDF here).

Materials:

• Japanese size 4 & 6 (3.3 & 3.9 mm) double-pointed needles
• Japanese size 4 & 6 (3.3 & 3.9 mm) straight needles
• 300-350g yarn (between sport and DK depending on your gauge)

Gauge measurements are for larger needles.

NOTE: The website includes directions for three variations of the vest: Stylish Vest, Basic Vest, and Basic Sweater (i.e., Basic Vest plus sleeves). The Stylish Vest differs only by having ribbing all the way up the sides of the torso for a more form-fitting shape.
