Costume Construction & Fitting for Augmented Figures

Constructing costumes for augmented figures requires understanding how implants interact with pattern geometry, fabric behavior, and structural support. These techniques apply whether building from scratch, adapting commercial patterns, or altering finished garments.

Pattern Adjustments for Implants

The two primary pattern adjustments for augmented figures are the Full Bust Adjustment (FBA) — which adds width and depth at the bust apex for larger overall bust size — and the Upper Cup Adjustment, which adds ease specifically at the upper cup area to accommodate the upper pole fullness of high-profile implants. The FBA is well-documented in sewing literature. The upper cup adjustment is less commonly discussed but essential for high-profile augmentation where the standard FBA alone doesn't address the rounded upper pole.

Built-In Support for Cosplay Costumes

Cosplay bodices for augmented figures should include built-in support rather than relying on an external bra. The most effective approach is a layered inner bodice: a structural layer with full steel boning at vertical channels and underwire at the under-bust line, encased in a fitted lining, with the outer fashion fabric attached to the lining surface. This inner bodice approach — standard in theatrical and bridal construction — distributes implant weight across the entire costume structure. Chimera Costumes documents this technique in detail on their website (chimeracostumes.com).

Fabric and Material Choices

For augmented figure costumes, fabric selection matters more than it does for standard sizing. Stretch fabrics (ponte, jersey, power net) accommodate the projection geometry of implants without requiring precise pattern matching. Power net or swim lining as an underlining layer prevents distortion of the fashion fabric under the weight of implants and extends the costume's structural life significantly.
