From the outer corners of your grid, calculate the specific drop points for the front and back waist curves. Next, draft the leg curves. The front leg curve is cut significantly deeper toward the center to accommodate the natural forward stride of the leg, while the back curve offers more coverage across the glutes. Step 4: Isolate the Gusset

: Deep dives into wire-frame theory, cup shaping (including multi-part cups), and how to achieve support through structural seams rather than just elastic.

Underwear relies on exact measurements and understanding fabric stretch to avoid discomfort.

If you are working on a specific design project right now, I can help you apply these principles. Tell me:

Kristina Shin’s approach simplifies the mathematical complexities of intimate apparel through step-by-step drafting formulas. The methodology focuses heavily on practical application:

The guide is structured to take a designer from basic theory to industry-ready patterns. 1. Measurements & Foundation Provides tables for both scales.

Shin provides exact mathematical ratios to calculate horizontal and vertical contraction without distorting the design lines. 2. The Architecture of the Bra Block

: Keep vector points minimal around tight leg curves to ensure smooth cutting paths.

: A simple ruler setup measures exact fabric elongation percentages. The Draft: Step-by-Step Brief Pattern Construction

Separate the lower crotch section to create the gusset pattern piece. Add seam allowances to the front and back attachment points, ensuring the lining piece mirrors this shape. Fabric Dynamics and Stretch Calculation

Note: When acquiring digital educational resources, ensure you are supporting the author and academic publishers by purchasing verified, legal e-book or PDF editions through authorized academic distributors and global booksellers. Essential Tools Needed to Follow the Book

Measure the hip (say, 36 inches). Measure the fabric’s stretch (if 6 inches stretches to 9 inches, that is 50% stretch). Shin’s formula: Pattern width = (Hip ÷ 2) × (1 - (Stretch % x 0.8)) . You apply negative ease so the underwear stays on without elastic squeezing too hard.
