#19 How to Solve for Fit Before You Sew

One of the most efficient ways to avoid making endless samples is by assessing your sewing pattern before you cut your fabric. In this video tutorial, I walk you through how to do just that using the Belle Blouse sewing pattern—but the techniques apply to nearly any commercial pattern.

Why Assessing the Pattern First Matters

Sewing a garment that fits well doesn’t start at the sewing machine—it starts at your cutting table with the pattern itself. By reviewing the pattern’s sizing chart and comparing it to your personal body measurements, you can anticipate the fitting changes you'll need and make adjustments right away. This simple step often saves an entire muslin.

What You’ll Learn in the Video

In this video, you’ll learn exactly how to assess a sewing pattern for fit using real data—your own body measurements and the pattern’s specifications.

Here’s what’s covered:

• How to read a sewing pattern sizing chart

• Why finished garment measurements matter

• The importance of body proportion (not just bust, waist, and hip)

• How to measure length segments like center back neck to waist and waist to hip

• When and how to make vertical and horizontal pattern adjustments

• What balance lines are, and how to find them on your pattern

• How to make a basic cup size adjustment—even if your pattern has no darts

• How to measure the pattern for ease and determine if you need more room for comfort

These steps are outlined in the free Perfect Fit Guide, which I mention in the video. If you don’t have it yet, you can download it below.

How This Helps You

This approach is ideal for sewists who are tired of endless trial and error and want a clear, structured way to evaluate fit before cutting fabric. It’s especially useful if you're adjusting to a changing body shape or sewing for comfort while seated.

Learning to assess a sewing pattern before you sew gives you more control, reduces waste, and builds your confidence as a garment maker.
