The A-Line Skirt Pattern

The MiSlope A-line Skirt Tool generates a made-to-measure skirt using your waist, hip, and skirt length measurements, with precise control over flare, seam lengths, and finishing details.

How the Base Shape Works

• Waist measurement includes negative ease for a secure, snug fit

• Hip measurement defines the hemline when flare is set to 0

• Skirt length is controlled independently through seam lengths

With flare set to 0, the hem width equals the hip measurement, creating a clean A-line silhouette. The skirt remains fitted through the body while maintaining movement at the hem.

Skirt Flare

Flare controls the amount of volume added to the hem by increasing the hip measurement used in the pattern.

• 0% flare
  Hem width equals the hip measurement

• 50% flare
  Hem width equals hip + 50%

• 100% flare
  Hem width equals hip + 100%

Negative ease is never applied to the hip measurement. It is applied only to the waist. Increasing flare increases hem width and volume without affecting skirt length.

Seam Length Customization

Right Side Seam Length

Controls the skirt length measured along the right side seam, from waist to hem. This value determines how long the skirt is overall.

• When flare is set to 0, the hem remains equal to the hip measurement regardless of skirt length

• Increasing flare changes hem width and fullness, not seam length

• Length and volume are controlled independently

Left Side Seam Length

Controls the skirt length along the left seam, from waist to hem. This value is fully independent from the right side seam.

• The left seam is cut on the fold by default

• To create a uniform hem, set the left seam length equal to the right seam length

• Increasing the left seam length allows you to add length to the back panel while keeping the front and side seams aligned

Because the two right seams form the visible side seams, this setup lets you create back coverage or high-low silhouettes without disrupting fit.

For advanced customization, you can multiply the waist and hip measurements by four and choose not to cut on the fold. This unlocks asymmetrical designs, uneven hems, and more experimental silhouettes while using the same base pattern system.

Seam Allowance Controls

You can add custom seam allowances to:

• Hem

• Waistband

• Right side seam

This allows full control over construction preferences and finishing methods.
