Ridgeline Vest is a chic little waistcoat, worked bottom-up in allover ribbing for a sleek, tailored silhouette with clean lines and beautiful texture. It layers easily over tees, dresses, and tanks, making it an easy favorite for transitional weather.

We chose Katia Concept Cotton-Merino for its soft, structured feel: it gives the fabric beautiful shape and brings out the texture of the ribbing. Light yet sculpted, this yarn makes Ridgeline feel polished and wearable with just the right amount of hold. US customers can get 15% off with code WOOLANDPINE15 through August 31, and the pattern is 30% off through Monday, July 7. discount applied at checkout, no code needed.

Construction Overview

Ridgeline is knit seamlessly from the bottom up in 1x1 ribbing with a tidy i-cord selvedge. We recommend casting on with a smaller needle to avoid flare at the hem. After splitting for the underarm, you’ll shape each front separately before working the back last and finishing with a clean 3-needle bind-off at the shoulders.

Short rows add subtle shaping at the shoulders, and three buttonholes offer styling options for a modern waistcoat look.

Hot tip for crisp ribbing: A gentle tug after every knit—and especially every purl—can really clean up your stitches. No overthinking required.

Why You’ll Love It

• Sleek silhouette: Allover ribbing creates structure with flexibility.
• Smart layering: Designed to throw over just about anything.
