How to Make a Cup Size Adjustment on a Pattern without Traditional Darts


In the last video you got a sneak peek at the cup size adjustment I made on my sewing pattern. This week I’m going to show you exactly how to do it.

Before you make your cup size adjustment make sure you have completed any length adjustments you may need. Pattern adjustments are best approached in this order: length, contour, width, girth. You’ll find that working in this order will help you eliminate fitting issues one step at a time. You can find more details on fitting order and method in The Perfect Fit Guide. Get your copy HERE.

Watch the video to see how to increase the cup size of the Belle sewing pattern.

When you’ve completed the cup size adjustment, be sure to make the corresponding length adjustment to the front facing. Make it a habit to always consider the corresponding pattern pieces that may be affected by any pattern adjustment you make.

If you’d like to see how to reduce the cup size of the pattern, click HERE for a blog post on the topic. I hope you’ll find that helpful as well.

If you’re not sure what cup size to use for your pattern adjustment, be sure to watch Three Ways to Determine Your Cup Size. You’ll find a link to that tutorial on this page.

If you’re following along with this video series I hope you’ll join in on the conversation in the In-House Patterns Studio private Facebook group. You can ask questions and share your progress with others who are doing the same.

Next week, I will be sharing a styling tweak that I’ll be making to the Belle pattern to make it a little more versatile. I hope you’ll tune in.
