Kristina Shin's Approach

Unfortunately, I couldn't find a direct link to a free PDF version of "Pattern Making for Underwear Design" by Kristina Shin. However, you can try searching for the book on online retailers such as Amazon or Google Books, or check with your local library or fashion school to see if they have a copy of the book. You can also try contacting Kristina Shin directly or checking her website to see if she offers a digital version of the book.

The "story" of this book is centered on a radical shift in perspective. Instead of starting with a shirt pattern and working down, Shin’s method starts with the underwire shape The Foundation:

  • Avoid downloading pirated PDFs from file‑sharing sites; those are illegal and risky (malware, poor-quality scans).

    • Take the following measurements to create a basic underwear pattern:

    Key patternmaking principles (practical, followable)

    1. Start from a reliable block: Use a basic underwear block (brief, bikini, high-waist, or boxer brief) matched to the body’s measurements—waist, hip, rise, thigh circumference.
    2. Measure for stretch: Record fabric stretch percentage across both directions and calculate ease based on desired finished measurements (negative ease for snug fits).
    3. Map seam tension: Identify seams that will carry tension (waistband, leg openings, crotch seam) and plan reinforcement: stay-stitching, elastic channels, or folded facings.
    4. Draft the crotch carefully: Crotch shape and length determine comfort; test with toile and adjust the rise and curve rather than only adding width.
    5. Use anatomical shaping: Add small darts, contour seams, or curved panels to follow pelvic and gluteal contours for better fit and reduced fabric movement.
    6. Plan elastic attachments: Choose top-stitched, enclosed, or picot elastic methods and add appropriate allowances or fold lines in the pattern.
    7. Prototype iteratively: Make quick toiles in a stable knit or mock fabric; mark pressure points and ride-up, then refine pattern in 1–3 small adjustments.
