A few questions, then the Nattern engine drafts your skirt.
Your pattern pieces
appear here
Skirts are drafted live by the Nattern engine from your answers, in centimetres and without seam allowance. When you are signed in to Claude, "Read my sketch" lets the AI suggest the skirt style and length from your drawing; always check its answers before you generate. Without it, choose the style yourself. Straight, A-line, flared and 4-panel skirts in woven fabric can be tried on the 3D fit form, adjusted there, then opened in PDS. Other garments come from the block library. Adjust any draft in PDS, then export PDF, SVG or DXF from there.
Photograph or scan a paper pattern piece, mark one measurement you know, trace its edge, and open it true to size in Nattern PDS.
We are finishing this feature. It opens after the first patterns and the app are live.
Tap the two ends of a length you know: a ruler, a tape, or one straight edge of the pattern. Drag a mark to fine-tune it, then type the length.
Your true-size piece
appears here
The piece is scaled from your one measurement, in centimetres, with no seam allowance added. A photo taken at an angle stretches the shape, so check one more edge against the paper pattern in PDS before you cut. One piece per photo.
Send your measurements and a note about the style. We draft a skirt pattern to your body and deliver it as PDF and DXF. Not sure how to measure? . Other garments follow in later waves.
Fill in the form with your waist, hip and length.
Drafted to your numbers, with one free adjustment.

Bust: the fullest part of the chest, tape level across the shoulder blades. Waist: the narrowest natural point, tape level and slightly loose. Hip: the fullest part, about 20 cm below the waist, feet together.
Choose by your bust for tops and dresses, and by your hip for skirts and trousers. If your bust, waist and hip fall two or more sizes apart, a made-to-measure pattern will fit you better than a chart size.
These are body measurements, not garment measurements. Equivalents between countries are approximate because brands differ. Our patterns add ease for the style.
Nattern sizes are our own, set from a comparison of leading international size charts and tuned in fit tests. Letter sizes are approximate.

Patterns you buy are for personal use. Selling garments made from a pattern needs a commercial licence, which the Pro and Studio plans include. The full licence is published when sales open.
Patterns are drafted in centimetres without seam allowance unless stated. Print the test square first to check the scale. Body measurements differ, so a made-to-measure pattern is the closest fit.
