The West Sewalong is a step-by-step video series designed to guide you through sewing the West, from choosing your size to finishing the final details.
In this sewalong, we walk you through each stage of the process in short, focused lessons. You can move through the videos at your own pace, pause as needed, or skip ahead if you’re already comfortable with certain steps.
West is a button-up that effortlessly blends comfort with chic detailing. Its relaxed, oversized fit is perfect for easy layering and a laid-back look.
The back yoke adds structure, and delicate gathers at the front shoulder and center back below the yoke seam bring a touch of softness and movement. Practical and stylish, the West Shirt features cut-on sleeves, a notched collar, and two front patch pockets for a touch of utility and a modern fit.
To follow along, you’ll need the West Pattern. Seamwork members can download it as part of their membership, and non-members can purchase it individually in the shop.
Getting Started
Fabric recommendations: Look for light to medium-weight woven fabrics such as chambray, cotton lawn, shirtings, batiste, Swiss dot, linen, cotton voile, cotton gauze, rayon challis, rayon crepe, and silk.
Fabric qualities to look for: The West pattern is designed to be oversized, and it has cut-on sleeves. This means you’ll want a fabric with at least some drape so that the fabric hangs on your body and doesn’t stick out and look stiff.

Fitting Adjustments
We created a free downloadable PDF called the Four Height Zones to help you gather the information you need to make adjustments to your pattern where you need it. We recommend printing it out and writing your height measurements on it to keep in your sewing journal.
Compare these measurements to the corresponding landmarks on your pattern pieces, and you'll know how much you need to shorten or lengthen that part of the pattern.
