stretch block\u003c\/strong\u003e, is a foundational sewing pattern used to develop fitted garments that extend from the upper body through the legs.\u003c\/p\u003e\n\n\u003cp\u003eUnlike a finished catsuit sewing pattern that includes specific styling features, such as a predetermined neckline, open back, or panel construction, a catsuit block focuses on the underlying shape and proportions of the garment.\u003c\/p\u003e\n\n\u003cp\u003eThe purpose of a block is to give you a starting point for developing your own designs. Instead of repeatedly modifying an existing commercial pattern, you can work from a foundation drafted using the measurements and stretch settings you choose.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eUse your Catsuit Block to develop:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eClassic dance catsuits and unitards\u003c\/li\u003e\n\u003cli\u003eCustom skating and performance costumes\u003c\/li\u003e\n\u003cli\u003eStretch bodysuits and fitted one-piece garments\u003c\/li\u003e\n\u003cli\u003eCustom neckline and back variations\u003c\/li\u003e\n\u003cli\u003ePanelled and color-blocked garment designs\u003c\/li\u003e\n\u003cli\u003eSleeved catsuits and mock-neck styles using compatible MiSlope drafting tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe Catsuit Block is intended for sewists and designers who want to take an active role in developing the final garment design. Additional pattern development may be required to create specific style lines, construction details, and finishing methods.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Choose a Custom Catsuit Block Instead of a Fixed-Size Pattern?\u003c\/h3\u003e\n\n\u003cp\u003eTraditional commercial sewing patterns are generally developed using a predetermined set of body measurements. While you can adjust those patterns, their original proportions are based on the sizing system selected by the pattern designer.\u003c\/p\u003e\n\n\u003cp\u003eMiSlope takes a different approach.\u003c\/p\u003e\n\n\u003cp\u003eRather than simply selecting a size and scaling an existing pattern, the Catsuit Block Tool uses your measurements to calculate the pattern geometry.\u003c\/p\u003e\n\n\u003cp\u003eThis allows you to account for individual differences in:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBust, waist, and hip circumferences\u003c\/li\u003e\n\u003cli\u003eUpper-body and lower-body lengths\u003c\/li\u003e\n\u003cli\u003eShoulder dimensions and slope\u003c\/li\u003e\n\u003cli\u003eArmhole depth\u003c\/li\u003e\n\u003cli\u003eFront and back crotch proportions\u003c\/li\u003e\n\u003cli\u003eKnee and ankle measurements\u003c\/li\u003e\n\u003cli\u003eOverall body proportions\u003c\/li\u003e\n\u003cli\u003eHorizontal negative ease for stretch fabrics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWhether you are drafting for yourself, a dancer, a figure skater, or a client, the ability to control individual measurements provides a more personalized starting point than selecting a fixed-size sewing pattern alone.\u003c\/p\u003e\n\n\u003ch3\u003eDetailed Upper-Body Drafting\u003c\/h3\u003e\n\n\u003cp\u003eThe Catsuit Block uses multiple upper-body measurements to calculate the foundational shape of the garment.\u003c\/p\u003e\n\n\u003cp\u003eThese include bust circumference, bust span, waist-to-bust length, neck circumference, shoulder length, nape-to-waist length, shoulder slope, and armscye depth.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOptional Bust Radius:\u003c\/strong\u003e Enter the bust radius measurement to provide additional information about the shape and projection of the bust.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOptional Shoulder Slope:\u003c\/strong\u003e Use a measured shoulder slope angle to personalize the relationship between the neck and shoulder point. The tool includes a shoulder slope calculator that uses shoulder length and shoulder drop measurements.\u003c\/p\u003e\n\n\u003cp\u003eThese drafting inputs help establish the upper-body foundation for further development into fitted stretch garments, including dance unitards and custom performance costumes.\u003c\/p\u003e\n\n\u003ch3\u003eIndividualized Lower-Body and Crotch Curve Drafting\u003c\/h3\u003e\n\n\u003cp\u003eAccurate lower-body proportions are an important part of drafting a fitted catsuit, particularly when developing garments that extend continuously from the shoulders through the crotch and legs.\u003c\/p\u003e\n\n\u003cp\u003eMiSlope uses detailed lower-body measurements, including waist, hip, waist-to-hip length, waist-to-waist length, front

Proportions:\u003c\/strong\u003e The front waist-to-perineum measurement establishes the front portion of the crotch curve, while the waist-to-waist measurement provides the overall length from center front to center back through the crotch.\u003c\/p\u003e\n\n\u003cp\u003eUsing these measurements allows the drafting system to establish the front and back proportions according to the wearer's measurements rather than relying entirely on standardized proportions.\u003c\/p\u003e\n\n\u003cp\u003eThis is especially relevant for custom-fit stretch garments, where differences in torso length,

the horizontal negative-ease percentage used to generate your Catsuit Block.\u003c\/p\u003e\n\n\u003cp\u003eNegative ease reduces the pattern's horizontal dimensions relative to the wearer's body measurements, allowing suitable stretch fabrics to conform to the body.\u003c\/p\u003e\n\n\u003cp\u003eThe Catsuit Block Tool supports horizontal negative-ease settings from \u003cstrong\u003e0% to
