Drafted · Pinned · Cut

In testing · Invite only

Sewing patterns drafted to your measurements.

Not graded up and down from a size chart.

Commercial patterns start from a fit model who isn't you, then get scaled to a size that also isn't you. Sloper Studio starts from your body and drafts the pieces from scratch, so the fitting happens before you cut, not after.

Access is invite-only while we test. Testers get free custom-fitted patterns and are compensated for feedback.

Every piece ships with the drafted seam line, the offset cutting line, grain and balance notches.

How it works

Three steps from a tape measure to a pattern you can cut.

Choose a garment and fabric

Pick from eight garments, then set your fabric: woven, stretch or knit. Ease, darts and seam allowances all adjust to match.

Where we actually are

The engine works and it drafts real patterns. What it hasn't done yet is prove itself in fabric on enough bodies. That's the part we're doing now, and it's the reason sign-up isn't open.

We'd rather tell you that than sell you a pattern that doesn't fit.
