Adding Ease to Your Garment

A few years ago, I adapted my knit Grainline Studio Morris blazer pattern so I could make it with some luscious silk matka. I knew I had to adjust the pattern since my fabric of choice had absolutely no stretch in it. I decided to take a tried-and-true (TNT) pattern designed for a woven fabric and “frankenpattern” the knit blazer into a woven blazer. I took some of the pattern pieces from the Archer Buttonup pattern (also designed by Grainline) and came up with new cutting lines for the Morris. I used the Archer upper back, arm scythe, and upper sleeve to redraft the blazer pattern and was just sure I had made all the pattern adjustments to shift from a zero-ease design that works with the stretch of a knit to a design that would work with a non-stretch woven. I finished the blazer and couldn’t wait to put it on only to discover it was a bit too tight across the upper back. I hadn’t added enough EASE! I know I am not the only person who has experienced this.

Can We Put Your Mind at Ease?

We’d like to put your mind at ease with some information and a free garment ease template created by members of the Plano, TX chapter that shows the minimum amount of ease you’ll need to add in your garment for a comfortable fit. Identifying the correct amount to include is vital to avoid an outcome like the one in my blazer story.  We hope this ease cheat-sheet helps you!

What is ease?

In its simplest form, ease is the additional room in a garment in excess of the actual body measurement. There is much more to ease than this simple definition though — there is wearing ease, design ease and negative ease. Each of these impacts the finished measurement of a garment in different ways.

• Wearing ease provides ease of movement. It is the difference between the actual body measurement and the finished garment measurement. The template will help you understand this kind of ease. It gives you guidelines that will help you be sure you have at least enough room in your garment for comfortable movement as you wear it.
• Design ease provides the style. It is also referred to as style ease or fashion ease. It is additional ease added beyond what is needed for movement to create specific styles ranging from close fitting to very loose-fitting garments. It also comes into play when the design of the garment includes things like pleats, gathers, or tucks.
• Negative ease is associated with fabrics that stretch (such as knits or woven fabrics with lycra added) or are cut on the bias, producing a certain degree of stretch. In this case, the finished garment measures the same as the actual body measurements, or more often, even smaller. The degree of stretch produced in each fabric plays a big role in how much negative ease a garment will need for good fit. Negative ease is used in garments like activewear and swimwear.

How do I calculate the right amount of wearing ease?

When choosing the size you will make in a pattern, look not only at the body measurements, but also the finished garment measurements. Many patterns will include this information for at least the 3 primary measurements – bust, waist and hips. If your pattern does not include this information on the pattern, you can calculate it yourself by simply measuring the pattern pieces in those locations and removing the amount included for seam allowances. Compare the finished garment size to your personal body measurements to be sure you will have a comfortable fit before you start cutting.

More about Negative Ease

As already stated, negative ease simply means that your finished garment measurements will be the same or smaller than your actual body measurements. When sewing with knits or stretch woven fabrics, the same accommodation for wearing ease is not required since the fabric will stretch as the body moves. Just because your finished garment is smaller than your actual body measurement doesn’t mean you won’t be able to get it over your head. The more negative ease you incorporate just means you will get a more fitted look in the final garment. In most cases, you will probably target no more than 1”-3” negative ease in your design. More than that and you may wander into that “Incredible Hulk” look that has people wondering if you will burst through the seams at any moment.

Of course, the percentage of stretch in your fabric choice and whether it has 2-way or multi-directional stretch play a huge role in determining the right amount of negative ease. The higher the percentage of stretch built into the fabric you have chosen for your project, the higher the percentage of negative ease you are likely to need in your pattern.

Don’t forget Design Ease

With all this talk about negative ease, let’s not leave this discussion without going back to the concept of design ease. Even with stretch fabrics, design ease has a role to play. It is perfectly acceptable to decide to add design ease into a garment made with a very stretchy fabric. It will take your garment from form-fitting to soft, graceful drape and still have a beautiful look. You are the designer and you are in charge!

Now it’s you turn!

We hope this gets you started on your journey of understanding ease and fit. This is a topic often discussed in ASG monthly group meetings around the country. Many groups focus on this kind of topic frequently and would love to meet you. Talk to someone in your local chapter to find out what is happening there. ASG loves to walk alongside fellow sewing friends in their sewing journey!
