Bootstrap Fashion and Ourlette both give you a pattern drafted to your measurements, but the design comes from different places. Bootstrap Fashion sells a catalog of fixed designs that it drafts to the measurements you enter, one pattern per purchase. Ourlette drafts a pattern from a photo or a description you provide and lets you change its options. If the design you want is in the catalog, Bootstrap Fashion is a straightforward choice; if you are starting from an image, Ourlette is.

How does Bootstrap Fashion work?

Bootstrap Fashion runs an online shop of custom-fit sewing patterns. At the time of writing (October 2026), you choose a design, enter your body measurements following its measuring instructions (or pick a standard size), pay for the pattern and receive the files by email, usually within half an hour. Files are offered for home printers (A4, Letter and other sizes), for large-format printing and for plotters, in PDF, PLT or DXF. Bootstrap Fashion is particularly known for its made-to-measure DIY dress form patterns, which let you sew a dress form shaped like your own body. It also sells through an Etsy shop.

The catalog runs to hundreds of designs. Because each design is fixed, what you customize is the fit, not the style.

How does Ourlette work?

Ourlette starts from what you want to sew: a photo, a screenshot, a link to a public Pinterest pin, Instagram post or shop page, or a description. The AI identifies the garment and its details and uses the matching garment type from Ourlette's catalogue with its options, or, on the Maker and Atelier plans, has its AI pattern maker draft a new pattern piece by piece (on the Free plan, Ourlette suggests the closest tested models and Community patterns to start from). A drafting engine then draws the pieces from flat-pattern blocks with your measurements and the right ease.

You can change the design afterwards: lengthen the skirt, swap the sleeves, change the neckline or the fit, and the pattern redraws at once. A 3D mannequin built from your measurements shows the silhouette, in a plain color or in the print from your photo (a preview, not a fabric simulation). On a paid plan you print at true scale on A4, US Letter, A3, Tabloid, A0, 36 × 48 in or for a projector, with the sewing guide as a PDF.

When is Bootstrap Fashion the better choice?

  • The design you want is in its catalog. You get that exact design, drafted to your measurements, with no need to describe it.
  • You need a dress form. A made-to-measure dress form is a Bootstrap Fashion specialty; Ourlette has none in its catalogue.
  • You want a ready design for a garment outside Ourlette's catalogue. Ourlette's AI pattern maker can draft tailored blazers, corsets, lingerie or swimwear on the Maker and Atelier plans, but as new designs no one has sewn yet; a catalog design you can see in drawings and photos first may feel safer.
  • You prefer to pay per pattern. If you sew a few garments a year, buying the ones you need can cost less than a subscription.
  • You use a plotter or CAD software. PLT and DXF files are available; Ourlette exports PDFs and a projector file only.

When is Ourlette the better choice?

  • You are copying a look. Starting from the picture saves you hunting through a catalog for something close.
  • You want to adjust the design. Options such as length, neckline, sleeves and fullness are part of the pattern, and you can try them before printing.
  • You want to see it first. The 3D preview on your measurements helps you judge proportions, for example where a hem falls on you. Read more in why see your garment in 3D before you cut.
  • You want a guide for your version. Ourlette's guide covers the steps for your options, the pieces with cut counts, notions such as zip and elastic lengths, cutting layouts and fabric quantities for 110, 140 and 150 cm (45, 55 and 60 in) wide fabric, and you can ask it questions while you sew.
  • You sew often. The Maker plan, at $7.99 a month or $59 a year, includes 30 AI patterns a month (3 of them exact designs) and printing for every pattern you make.

What do they share, and what are the limits?

Both depend on your measurements. Take them carefully with a tape measure, ideally with help; our measuring guide explains each one. Both are drafted by software rather than fitted on your body by a person, so a toile remains the safest step for fitted garments.

Bootstrap Fashion's limit is that the style is fixed: if your dream dress is not in the catalog, you adapt the closest design yourself. Ourlette's limit is that only its 36 catalogue garment types are tested: anything else is a new design from its AI pattern maker, so make a toile first. Printing requires a paid plan.

Can you use both?

Yes. A made-to-measure dress form is a useful companion to any made-to-measure pattern, including Ourlette's: you can check a toile on it when there is no one around to help with fitting. You might also buy catalog designs for the garments you would rather not sew from an untested new design, and use Ourlette for the looks you find in photos.
