How to sew a Circle Skirt

Updated: May 8

In this tutorial, we are going to be drafting the classic circle skirt. So-called because the waistline and the hemline are circular. This makes the skirt fitted at the waist and full at the hem. The pattern is versatile as it can be used to make not only skirts but also, tops, flounces, trains, sleeves and even dresses. We shall concentrate on how to draft the full and half circle skirt in this tutorial.


Mathematical Formula



The Formula for the circumference of a circle is 2πr. In the illustration above, if we assume the Circumference of the Inner circle is the Waist, then the formula would be;


2πr = Waist. The Value of π is 22/7 or 3.14. Therefore 2 x 3.14 x r = Waist.


Now we have to find the value for R i.e. the Radius as the unknown value because the radius is required to draw a circle (or waist in this case) Therefore;


R= Waist ÷ (2 x 3.14) Or Waist ÷ 6.28


In conclusion the formula for drafting a full Circle Skirt = Waist ÷ 6.28



It follows also that the formula for drafting a half circle skirt = (Waist x 2) ÷ 6.28


How to Draft Full Circle



  1. Use the formula above to calculate the Radius.

  2. Placing a tape at the corner, mark out the radius from the point going from one edge to the other. This will be the waistline. Label as Points A and B

  3. Add seam allowance for the waist above the waistline

  4. From Point A, measure down the length of the skirt. Going along the waistline, mark the length of the skirt until you get to point B.

  5. Add Hem allowance below the Hemline.

  6. This creates a quarter of the full circle pattern


How to draft Half Circle



  1. Use the formula above to calculate the Radius.

  2. Placing a tape at the corner, mark out the radius from the point going from one edge to the other. This will be the waistline. Label as Points A and B

  3. Add seam allowance for the waist above the waistline

  4. From Point A, measure down the length of the skirt. Going along the waistline, mark the length of the skirt until you get to point B.

  5. Add Hem allowance below the Hemline.

  6. This creates half of the half circle pattern


NOTE: that the waistlines are the same measurement, but one pattern is a full circle and the other is a half circle.


Variations of the Circle Skirts


1. The above method makes a circle skirt without any seam lines. Now if you want to have perhaps side seams or a centre back seam, you have to add the seam allowance to the waist measurement before calculating the radius. For example;

a) Centre back seam - plus 1 inch

b) Centre back and two side seams - plus 3 inches

c) Two Side seams- plus 2 inches

2. For the Half circle skirt, one side will naturally be open already, so you should include the seam allowance for joining it together at least. You can also split it into 2 parts for a separate front and back piece, making sure to add the seam allowance before calculation.


How to Layout on Fabric

  1. Full Circle - Fold fabric in half, then half again, to make four layers, then place pattern, aligning the Centre front and the sides accordingly. If you are splitting the circle into a separate front and back, you can do so after cutting out the full skirt.

  2. Half Circle - Fold fabric in half, to make two layers. Place pattern, aligning the Centre front and the sides accordingly. If you are splitting the circle into a separate front and back, you can do so after cutting out the full skirt.


Waistband



1. For a simple straight waistband draft a rectangle using;

Length = Waist length + 1inch (2.5cm)

Width = width of waistband x 2

2. Add seam allowance on all sides of the waistband pattern
