The Sage Sewalong is a step-by-step video series designed to guide you through sewing the [pattern], 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.
Sage is a fitted button-up with a beautifully tailored bodice featuring princess seams and a subtly shaped center front hem. The neckline is meticulously finished with lining on the center front and back panels. A sewn-on placket with buttons adds a touch of classic detailing, while the full sleeves, gathered at the hem with an elastic casing, create a dramatic yet graceful effect.
To follow along, you’ll need the Sage 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 lightweight or medium-weight woven fabrics such as cotton lawn, cotton gauze, voile, chambray, swiss dot, rayon challis, linen, rayon crepe, and silk.
Fabric qualities to look for: It’s important to consider a fabric’s drape when sewing this top. Princess seams look lovely in drapey and more structured fabrics, but the garment will hang differently on your body depending on the fabric.
Drapier fabrics like rayon and silk will hang nicely on your body, creating a more flowy silhouette. Fabrics with less drape, like linen and lawn, will emphasize the princess seams and appear more tailored.

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.
