The Curvy Fitting Challenge
A curvy figure — characterised by significant bust-to-waist and waist-to-hip differences — presents fitting challenges at every pattern seam. Commercial patterns are drafted for figures with more consistent measurement differences between sizes, creating predictable problems at larger curves: bodice patterns that fit the bust will be too wide at the waist; skirt patterns that fit the hips will be too wide at the waist; and dresses that attempt to cover both often compromise the fit of each.
The solution is systematic: address each fitting area separately, adjust the pattern to accommodate the actual measurements at each point, and use construction techniques that allow independent fitting at each curve.
Princess Seam Construction
Princess seam construction is the most powerful fitting tool for curvy figures. Instead of a single side seam, princess seam garments have a vertical seam running from the shoulder (or armhole) to the hem that passes over the fullest point of the bust and continues over the hip curve. This seam can be adjusted independently at the bust point, the waist, and the hip, allowing precise fitting at each curve without affecting the others.
Converting a pattern without princess seams to one with princess seams: draw the proposed seam line on the pattern from the shoulder or armhole, through the bust apex point, and continuing to the hem; cut along this line; add seam allowances to both edges; and construct with the additional seam. The result is a bodice or dress that can be fitted precisely at every curve.
Waist Shaping Techniques
Achieving a defined waist in fitted cosplay garments requires waist shaping — either through seam curves, boning, or both. For woven fabric garments: curve the side seams and princess seams inward at the waist by the amount of waist suppression required (typically 2-4cm on each seam for a defined waist). For stretch garments: the elastic properties provide natural waist definition; additional elastic sewn at the waist seam increases the definition.
Boning at side seams creates a more structured waist definition — the boning resists the natural tendency of fabric to drop from the bust and splay outward at the waist. Steel spiral boning at side and princess seams in combination with good seam shaping produces the clearest waist definition in fitted bodices.

Frequently Asked Questions
A princess seam runs vertically from shoulder to hem through the bust apex, creating multiple seams that can each be adjusted independently. This allows precise fitting at the bust, waist, and hip separately — the most effective fitting tool for pronounced curves.
Take in 2-4cm at each seam (side seams and princess seams) at the waist level for a defined waist. Fit in a toile to find the right amount — it varies significantly by figure and by how defined the character's silhouette should be.
