How to make a skirt pattern like an expert 2


If you want to know how to make a skirt pattern that fits your measurements, here is a post that might help. There are a lot of types of skirts that you can make. But the basic one is the straight skirt.

Once you’ve made your custom pattern that fits, you can easily modify it into other types of skirts like a pencil skirt, A-line skirt, flared skirts of four, six and more parts, add a waistband or pockets, etc.

Even more,

If you know how to make a skirt pattern and a bodice pattern, you actually know how to make a dress!

In this post, I am going to show how to make the basic straight skirt.

Measurements for making the skirt

For the simple straight skirt, we are going to need waist, hips, waist to hips (hip depth) and overall length.

  • Waist
Measure the smallest part of the waist. Or, if you prefer the skirt to start lower on the hips, measure that circumference.
  • Hips
taking measurements for a skirt

Measure at the widest part of the hips. If you have a bigger belly, you should measure the circumference of your hips through the 

lower part of the abdominals (as shown on B on the right).

  • Hip depth

This is the distance between the waist and the wide part of the hips you just measured.

  • Length

Measure the overall length of the skirt on the outer leg. Start from the waist (or a bit lower if you prefer lower rise) and measure down as long as you want the skirt to finish.

You might want to add or remove a couple of inches for ease of movement. This depends on the fabric you are working with and the fit you want to achieve. So, there is not an exact number here.

In most cases, I don't add much ease, just don't take the measurements too tight on the body.

If you could use some help on ease, here is a great course on Pattern Drafting and Designing for Stretch Fabrics at BurdaStyle Academy. Among all other valuable skills learned, it explains ease and comes with a printable grader for different knit fabrics. 

What you are going to need

  • cut
    a big sheet of paper
  • cut
    grid ruler
  • cut
    paper scissors

Drafting the skirt sloper (option 1)

Outline the pattern

Draw an AB line that goes 1/4 the hips measurement. Draw the vertical BC line that equals the length of the skirt. Make the ABCD rectangle (figure 1). The AD line is going to be the center front/back fold of the skirt, so you might make it with a dotted line or mark the fold as you prefer.

Starting from points A and B down, apply the hip depth and mark the hip line with a dotted line.

This is going to form the frame of the sloper.

The next step is to shape the skirt at the waist.

From point A towards B mark 1/4 waist measurement plus 1 inch (2.5 cms) for the dart. 

Put a mark there (figure 2).

In most cases one dart is enough for a standart waist to hip ratio.  If the difference between waist and hips is small, I would skip the dart altogether.

 If it happens to be significantly bigger, I put two darts to compensate. 

Consider that when drafting the pattern with your custom measurements.

Mark the darts and waist points

Measure 3/4 inches (2 cms) up from the waist mark and mark that as well (the X point on figure 3).

Measure the middle between A and B and mark that with 1. Do the the same on the hip line and mark point 2.

Connect points 1 and 2 with a line. This line is for the dart placement.

 To make a 1 inch wide dart (2.5 cms), we need to put marks in both directions at 1/2 inch (1.2 cms) from the middle point 1 (figure 3).

Now let's mark the dart's length.

 There are some formulas used in the pattern making books on how to calculate the darts’ length. I am going to skip those in order not to overcomplicate the process and share my way to do it. 

I make the darts on the front 3.5 inches (9 cms) long, and the darts on back 5 inches (12 cms) long. This works for 90% of our clients, no matter of their body structure. 

For the back darts, you can also use the highest point of the buttox for a starting point.

But,

darts are very often customized to get the best fit possible. We are going to show how when we discuss final adjustments later.

Now that we have all these marks, let's

Draw the pattern

Starting at the X mark, make a curve that ends at the hip line (figure 4).  You can use a french curve or just eyeball it. Continue down the rectangle until you reach point C. 

Then, we draw the dart legs. We do that by connecting the points for length and width on both sides of line 1-2.

Connect the X point with the outer dart leg with a staright line to shape the waist (figure 4).

Trace the rest of the pattern following the shape of the rectangle.

The AD line is the center fold of the skirt sloper. Our straight skirt pattern is ready.

Because it is essentially the same, you can use it for a front and a back pattern piece. Just make sure to adjust the length of the darts for front and back.

You might want to draw two separate pattern pieces for the front and the back.  I prefer to do this if I want to make a center back seam, make diffrent darts or pleats, and other design changes on the basic pattern. In that case you can follow the steps above and make two. 

Or,

If you would rather draft separate patterns for the front and back skirt details at once, follow these instructions:

Drafting the skirt sloper (option 2)

Outline the pattern

This method of drafting the skirt pattern resembles very much the one we followed to make the basic pants pattern.

  1. Start building the rectangle ABCD where A to B is 1/2 the hips circumference and A to D and B to C is the length of the skirt (figure 1).

You can draw AD and BC with a dotted line, because they represent the center fold of the front and back sloper.

Steps to follow:

how to make a skirt sloper

As in the previous example, we measure and apply the hip depth and mark the hip line with a dotted H1-H2 line. 

Measure the middle beween A and B and mark with 1. We measure the middle between C and D and mark with 2.  

Connect 1 and 2.

 Where the line crosses the hip line, we mark point 3.

Mark the darts and waist points

Mark the front and the back pattern piece, because we are going to make different darts (figure 2). 

That would be the only difference between them for that simple skirt.

If you have plans to create a different style out of it, however, having two separate pattern pieces can be of great use. For example, if you add pleats only at the front.

Next, we mark the center folds and the position of the darts.

Measure the middle between H1 and 3 and mark 4. Measure the center between 3 and H2 and mark 6.

Do the same on the AB line. Measure the center between A and 1 and 1 and B and mark those points with 5 and 7. 

Connect 4 with 5 and 6 with 7. Those two new lines mark the positon of the darts.

Next, we mark the position of the dart legs and the dart length. As in the example above, we mark 1/2 inch (1.2 cms) in both directions of points 5 and 7 and mark the dark legs.

Then, from points 5 and 7 down we measure and apply the darts length. These would be 3.5 inches (9 cms) long on the front sloper, and 5 inches (12 cms) on the back.

Mark the waist. Starting at A, measure 1/4 waist + 1 inch (2.5 cms) for the dart and mark. Do the same starting at B towards 1.

Starting at those two new marks, measure 3/4 inches (2 cms) straight up and mark with X (figure 2).

Draw the pattern

Starting at the X marks, make  curves that end at the hip line at point 3 (figure 3). Continue down the rectangle until you reach point 2. 

Then, draw the dart legs. We do that by connecting the points for length and width on both sides of lines 4-5 and 6-7.

Connect the X points with the outer dart legs with a staright line to shape the waist (figure 3).

Trace the rest of the pattern, following the shape of the rectangle.

Zippers and slits

To add a slit, you need to add some inches to the pattern. That’s why often skirts come with a center back seam.
If you make a pencil skirt, you don't want to restrict the movement of the legs. A slit will not only give more freedom for movement but will also add a nice finishing touch to the skirt. To add a slit just add a couple of inches (5 cms) starting at the hemline and finishing approximately 8 inches (20 cms) up (figure 5).

If you make the skirt with a center back seam, you can sew the zipper at the back. If your skirt comes with two side seams, put the zipper on the side seam.

Adding seam allowance

The amount of seam allowance depends on the way you are planing to sew the skirt. If you are going to use a straight stitch, leave 5/8 (1.5 cms) for seam allowance. If you are using a serger, leave 3/8 inch (1 cm) or even a bit less.

For hem allowance 1 inch (2-3 cms) is usually fine. You might leave more for lighter fabrics to get the fabric fall nicer, this is also up to you.

Add the seam allowance everywhere you are planning to have an assembling seam. If the pattern is to be used on a fold, don't leave seam allowance ther (figure 6A). If you are about to have a center back seam, leave seam allowance there (figure 6B).

How to add a  facing to a skirt

First, use some tracing paper to copy the upper part of the pattern (figure 7) and cut it out (figure 7-1). Then, close the darts (figure 7-2) and smooth the curves (figure 7-3).

Do the same for the front and for the back. 

Sew the darts, make the side seams and then assemble the skirt details with the facing ones.

How to add a waistband to a skirt

If you want to add a waistband to the pattern, follow the steps for making a facing.

But,

 instead of tracing and cutting additional pattern piece, just cut out the waistband from the main pattern (figure 8).

Do the same for the front and for the back. When cutting from fabric, you are going to need two front pieces and two (or four if you have center back seam in mind) back pieces.

If you want a more narrow waistband (let's say 2 inches/5cms), cut trough the pattern as long as the waistband would go (figure 8A). Then, close the darts and smooth the curves (figure 8 - 1,2 and 3).

Don't forget to add seam allowance everywhere that you are supposed to make a seam. There is a good course on sewing waistbands and zips for beginners that you might like.

how to add a waistband to a skirt

If you would rather make a wider waistband, there would be too litlle of the dart left on the main pattern piece (figure 8B). I would skip making the dart and take in a bit at the side seam if necessary to match the pattern details of the skirt.

Follow the steps above for the actual waistband pattern piece (figure 8 - 1,2 and 3).

Always use interfacing for a pretty and stable waistband.

I would love to hear what you think.
