About this app

Tailor Base Patterns drafts sewing patterns to your own body measurements: bodice blocks, sleeves, skirt blocks and a choice of skirt and dress models.

Instead of picking the nearest standard size and fixing the fit afterwards, enter your measurements and preview a pattern drafted for your body. Build your own designs from a basic block (sloper), or choose a skirt or dress model and customise its options.

WHAT YOU CAN MAKE
• Bodice: front and back pieces
• Bodice + Sleeve: with a one-piece sleeve drafted to the bodice armhole
• Skirt base block: front and back pieces for your own designs
• Skirt models: pencil, A-line, flared, godet, slip, and half-circle, full-circle or double-circle skirts
• Dress models: combine any top (neckline, darts) and the skirt type and connect them at the waistline

CHOOSE YOUR SKIRT
• Flared skirt: choose slight, medium or full flare
• Godet skirt: choose 4, 6 or 8 panels, where the godets begin, and their flare angle
• Circle skirts: choose half-circle, full-circle or double-circle fullness using just your waist measurement and skirt length
• Add a waistband, side pockets or choose the zipper position where supported by the model
• See model pictures and short sewing notes to help you choose and sew

A REAL DRAFTING METHOD
The bodice and fitted skirt blocks use the EMKO CMEA pattern-drafting method, developed for garment manufacturing. Circle skirts are drafted geometrically from the waist and length.

For bodice drafting, the app goes further than scaling a block from bust, waist and hip:
• Four separate bust measurements to account for bust shape
• Automatic posture detection (Normal, Hunched forward, Hunched back), with the draft adjusted to match
• Waist ease shared across darts and seams
• Choice of garment type (dress or blouse, blazer, coat), fit level, fabric thickness and shoulder padding

EASY TO MEASURE
• An illustrated guide for every measurement
• Works in centimetres or inches
• Each skirt model asks only for the measurements it needs
• Checks help catch measurements that do not fit together before you generate
• Standard sizes available: XS to XL for bodice blocks and XS to L for skirts
• Try the built-in Sample Person to explore the app
• Preview your pattern for free; credits are required to download pattern files

SAVE YOUR WORK
• Save named measurement sets, for example one per client or family member, and reuse them any time
• My patterns: re-download your patterns for 30 days

PRINT-READY FILES
• A4 PDF: tiled pages with an assembly guide and a print-check square
• Plotter PDF: for wide-format printing; wide skirt pieces may be split into tiles with join lines
• SVG: a scalable vector file for compatible pattern-editing software
• Seam and hem allowances included, with cutting lines, sewing lines, grain lines and notches

GOOD TO KNOW
• Check the allowances marked on your pattern before cutting.
• A pattern is only as accurate as the measurements it is drafted from. Take each one carefully.
• Make a test garment and fine-tune the fit before cutting your final fabric.
• Circle skirts can stretch on the bias. Let the skirt hang before levelling the hem; follow the model's notes.

Made for people who sew and draft: home sewists, tailors, pattern makers and fashion students.

What’s new

New: Dresses. Pick Dress on the home screen to get a bodice and any skirt (pencil, A-line, flared, godet, slip, sun) drafted together, with optional sleeves, neckline and chest dart pictures, and a zipper at the centre back or the side seam. Standard sizes XS-L.

Also: the Bodice card now includes the sleeve. Tick "Add a sleeve" above the measurements.

Always prefer to use your own measurements instead of selecting a standard S/M/L sizes. The standard sizing does not guarantee the perfect fit.
