Kamal Kulshreshtha, with the help of unpaid Artificial Intelligence, learnt how make a skirt.
I used unpaid Artificial Intelligence (AI) to tell me how to make a skirt and to find out how much fabric would be needed for a 170cm tall woman having waist of 28†and hips at 40â€. Here’s what I got:
To generate a cut pattern for a long, flowing skirt for a woman with a height of 170 cm, a waist measurement of 28 inches (71 cm), and hip measurement of 40 inches (102 cm), I’ll first outline the basic pattern pieces needed. A simple long skirt can be either a circle skirt, half-circle skirt, or gathered skirt. Given the flowing style, a circle or half-circle skirt might work well.
Here’s an overview of the pieces for a half-circle skirt:
- Waistband: A simple rectangle matching your waist measurement.
- Skirt body: The flowing skirt part cut in a half-circle shape.
Calculations for the half-circle skirt
Waist radius: The radius for the waist is calculated using the formula for the circumference of a circle:
Waist Circumference 71
Radius = ————————– = ——– ~ 11.3 cm

Skirt length: Since the woman is 170 cm tall, and the skirt should be long and flowing, let’s assume you want the skirt to be about ankle length. You could subtract a few centimeters for the waistband, so the skirt length could be around 100 cm.
Total radius: The total radius of the skirt, from waist to hem, including the waist radius and the length, will be:
Total Radius = Waist radius + Skirt length = 11.3 cm + 100 cm = 111.3 cm
Cutting the pattern
Pattern shape: The pattern will resemble a half-circle, with the inner radius being 11.3 cm (waist) and the outer radius being 111.3 cm (total length). You’ll cut two pieces of this half-circle shape to form the front and back of the skirt.
Waistband: A waistband of about 71 cm long (plus seam allowance) and 5-10 cm wide would be cut as a rectangle.
Then the AI offers to give a helpful visual
Then I asked AI to make some adjustments. I asked it to give the cut pattern measurements for waist 30†instead of 28â€. Sure enough, it complied with the needed adjustment as below.
Sure! Here are the updated dimensions for the half-circle skirt with a 30-inch waist (76 cm)
Waist radius: The radius for the waist is calculated using the formula for the circumference of a circle:
Waist Circumference 76
Radius = —————————- = ——– ~ 12.1 cm
                                   2π                        2π
Skirt length: Since the woman is 170 cm tall, and the skirt should be long and flowing, let’s assume you want the skirt to be about ankle length. You could subtract a few centimeters for the waistband, so the skirt length could be around 100 cm.
Total radius: The total radius of the skirt, from waist to hem, including the waist radius and the length, will be:
Total Radius = Waist radius + Skirt length = 12.1cm + 100cm = 112.1 cm
AI also tells you what width of fabric you need to have to cut out this pattern.
Fabric width requirement: Since you’re making a half-circle skirt, you’ll need fabric with a minimum width of:
Fabric Width = 2×Total Radius = 2×112.1 cm = 224.2 cm
A word about the waistband too:
Waistband: The waistband would be a rectangular strip approximately:
- Length: 76 cm (waist circumference)
- Width: 5-10 cm (depending on the desired waistband height)
AI also gives you ideas for print design. Â Some of these looked like above.
