Learn how to lengthen or shorten a skirt or dress sewing pattern with this video tutorial by Sew DIY Patterns.

Today, is the final video in my series of how to adjust the length of different parts of a pattern. I hope that this will be a useful series for you as you move through your sewing journey. Today’s video tutorial will teach you how adjust the length of a skirt or dress. In the video, I’ll be using my Lou Box Dress 1 and an example A-line skirt to demonstrate both how to lengthen and how to shorten a skirt. If diagrams and written text are a better way for you to learn, I have those below the video. Happy sewing!

If the video above is not working, you can also watch on YouTube.

If you want to jump ahead, the shorten section is at time stamp 3:34 and the lengthen section is at 4:51.

Side note: How much you adjust the length will depend on the pattern, your personal measurements and personal preference. In this video, we'll focus only on how to make the adjustment properly. An easy way to find the length you want is to compare the pattern to a similar top that you like the length of.

How to shorten the skirt of a sewing pattern

Step 1: If your pattern does not have lengthen/shorten lines, you’ll need to draw one. Draw the lengthen/shorten line perpendicular to the grainline (or fold line). Cut the pattern along this line.

Step 2: Draw a guideline above the lengthen/shorten line, indicating how much you want to shorten the pattern. Overlap the pattern pieces, aligning the lower pattern piece with the guideline above and keeping the grainlines aligned.

Step 3: Redraw the side seam, smoothing out any jagged edges. Cut away any excess paper. You can use this pattern as is or trace it.
