Open Back Split Leotard Tool

The Open Back Split Leotard Tool combines MiSlope's customizable open-back leotard drafting system with a split bodice design, giving you a flexible foundation for creating color-blocked leotards, figure skating dresses, dance costumes, and performancewear.

Instead of working from a fixed-size sewing pattern, the tool dynamically drafts your pattern from your measurements, stretch percentage, and design selections. The split construction separates the upper and lower sections of the leotard, making it easier to mix fabrics, create contrast panels, and build more advanced costume designs from one customizable base.

For the ultimate figure skating and dance dress design system, we recommend pairing the Open Back Split Leotard with the FREE Circle Skirt Tool, Asymmetrical Skirt Tool, Collar Tool, and Sleeve Expansion Pack. Together, these tools allow you to build the leotard, sleeves, neckline, collar, and skirt components of your design while maintaining the same custom-fit MiSlope drafting foundation.

Key Features

• Split Leotard Construction: Separate the upper bodice from the lower leotard section to create contrast designs, color blocking, and more complex performance costumes.

• Designed for Figure Skating and Dance Dresses: Use the split construction as the foundation for adding skirts, sleeves, collars, and other design elements while maintaining the fit and structure of the underlying leotard.

• Open Back Customization: Control the depth and shape of the open back to create anything from a modest scoop to a dramatic low-back performance design.

• Gape Fix Option: Reduce unwanted gaping around the open back using MiSlope's automated pattern adjustment system, with options depending on your preferred back construction.

• Neckline Design Options: Create your split design with or without a contrasting neckline section depending on the style you are building.

• Strap and Shoulder Width Control: Adjust the upper portion of the leotard from narrower strap-style designs to fuller shoulder coverage.

• Compatible with the MiSlope Collar Tool: Combine your split leotard with the MiSlope Collar Tool to create high neck, mock neck, and other collar variations.

• Compatible with MiSlope Skirt Tools: Pair the leotard with the FREE Circle Skirt Tool or Asymmetrical Skirt Tool to transform your leotard base into a custom figure skating or dance dress.

• Compatible with the Sleeve Expansion Pack: Add sleeves to your design using the MiSlope Sleeve Expansion Pack for even more costume and performancewear combinations.

• Fully Integrated Measurement Logic: Draft using built-in ASTM Missy Curvy, Missy Straight, and Girls size tables, saved measurement profiles, or manually entered custom measurements.

• Leg Line and Armhole Customization: Adjust leg height, armhole depth, and other fit settings for the coverage and movement required by your design.

• Stretch-Specific Drafting: Build your pattern around your fabric's stretch percentage so the finished garment is drafted for stretch performance rather than relying on a fixed-size pattern.

• Seam Allowance Flexibility: Control your seam allowances for different areas of the pattern so you can adapt the draft to your preferred construction and finishing methods. YOU CHOOSE YOUR SEAM ALLOWANCE!

• Unlimited Pattern Variations: Return to the tool and generate new versions whenever your measurements, fabric, sizing, or design changes.

• Tiled Printing System: Generate cleanly labeled tiled pages for home printing, taping, and cutting.

Build Your Complete Figure Skating or Dance Dress

The Open Back Split Leotard is designed to work as part of the larger MiSlope drafting system. Start with your custom-fit leotard foundation, then combine it with additional MiSlope tools to expand your design possibilities.

• FREE Circle Skirt Tool: Add a classic skating or dance skirt to your leotard design.

• Asymmetrical Skirt Tool: Create more dramatic, directional, and competition-focused skirt shapes.

• Collar Tool: Add high-neck and collar variations to your design.

• Sleeve Expansion Pack: Add sleeves and expand the number of complete dress designs you can create from your base pattern.

Mix the tools you need for each design, change your measurements or fabric settings, and generate a completely new pattern whenever you want. This makes the Open Back Split Leotard especially useful for skaters, dancers, costume makers, and designers who need to create multiple unique looks without starting over with a completely different pattern every time.

Works Across Kids, Teens, and Adult Sizing

MiSlope is designed to grow with the wearer. In addition to drafting from custom measurements, the tool includes built-in ASTM sizing tables so you can generate patterns even when exact measurements are not available.

Draft using ASTM Girls sizing tables (sizes 2–20) for children and youth garments, making it ideal for dancewear, skating costumes, and growing bodies where consistent sizing is needed.

For teens and adults, you can draft using ASTM Missy Straight or ASTM Missy Curvy sizing tables, allowing you to start from an industry-standard proportion set while still maintaining stretch-specific drafting and negative ease control.

Whether you are sewing for children, teens, or adults, MiSlope provides a consistent drafting foundation across size ranges so you can design across multiple sizes without switching pattern systems.
