Lang PTO46-03 Vest Waistcoat Knitting Pattern

Lang PTO46-03 Vest by Lang Yarns

Garment Overview

The Lang PTO46-03 Vest, also known as the Langyarns Frida vest, is a classic knitted waistcoat designed for intermediate knitters. This sleeveless garment features a refined V-neckline and is constructed using a combination of flat and circular knitting techniques. Available in four sizes ranging from Small to Extra Large, with bust measurements from 42½" to 52" (108 to 132 cm), this vest offers a versatile layering piece suitable for various occasions and seasons.

Construction Techniques

The vest is worked using a bottom-up construction method, meaning the knitter begins at the lower edge and works upward toward the shoulders and neckline. The garment is primarily worked flat on straight needles for the front and back panels, which are then seamed together to form the finished piece. The V-neckline border is completed using circular knitting, worked in the round to create a seamless, professional-looking neckband.

Stitches and Pattern Details

The primary stitch pattern used throughout the vest is 1x1 rib stitch (alternating knit and purl stitches). This classic ribbed texture provides elasticity and a polished appearance. The rib stitch is worked on US 4 (3.5mm) needles, creating a structured fabric that hugs the body comfortably. The V-neckline features strategic decreases worked every round to create the characteristic V-shape, with decreases executed as slip 2 stitches together knitwise, knit 1, pass slipped stitches over (sl2tog knitwise, k1, psso).

Materials and Yarn Specifications

This pattern calls for Langyarns Frida, a premium yarn composed of merino extrafine fiber with superwash treatment and mulesing-free certification. The yarn is soft, breathable, and easy to care for. Yardage requirements vary by size: 400 grams (approximately 4 balls) for size Small/Medium, and 500 grams (approximately 5 balls) for sizes Large and Extra Large. The yarn is available in multiple sophisticated colorways, including brown-grey (1078.0007), petrol-grey (1078.0008), violet-green-blue (1078.0009), and brown-violet (1078.0010).

Needle Requirements

• Straight knitting needles: US 4 (3.5mm) and US 6 (4mm) sizes for working the main fabric
• Short circular knitting needle: US 4 (3.5mm) for working the V-neckline border in the round

Garment Dimensions

The finished vest measures 23½" (60 cm) in length from shoulder to hem. Bust measurements accommodate a range of body sizes: 42½" (108 cm) for Small, 45¾" (116 cm) for Medium, 48¾" (124 cm) for Large, and 52" (132 cm) for Extra Large. All measurements in the pattern are provided in metric (centimeters) as well as imperial (inches) for international knitters.

Shaping and Finishing Details

The vest includes tailored shaping at the V-neckline and shoulders. The front panels are divided at the center when the garment reaches 12½" (32 cm) in length, allowing each side to be finished separately. The left side features bind-offs at the beginning of right-side rows, while the right side features bind-offs at the beginning of wrong-side rows, creating a symmetrical V-neckline. Shoulder shaping is matched between the front and back panels for proper fit. The finishing process includes seaming the side seams and armhole edges, followed by picking up stitches around the neckline opening to work a ribbed V-neck border that measures 1½" (4 cm) when finished.
