Engineering Fit and Comfort in Luxury Bridal and Stage Costumes: Cutting Technologies, Materials Science and Multi-Stage Fitting

The article examines the technological aspects of creating luxury bridal garments and stage costumes under conditions of high customization. The aim of the study is to systematize engineering solutions that ensure stable fit, comfort, and visual expressiveness during prolonged wear, including dynamic performances. The methodology is based on an analysis of couture cutting practices, principles of corset base construction, fabric stabilization methods, and the organization of iterative fittings as a quality risk management tool. It is demonstrated that the combination of correct pattern balancing, functional layers (linings, meshes, reinforcements), calibrated hardware, and protocols for documenting changes during fittings reduces the volume of alterations and ensures predictable results. The practical significance of the study lies in the formation of a reproducible technological framework applicable to both bridal garments and costumes for stage performers.
