A structured two piece prom dress in cotton blend or structured knit works because the structure creates real shape and the two piece format means you are creating proportion intentionally. Structured fabrics hold their form and read as more interesting visually than fluid fabrics. Two piece dresses in structured materials usually have clean lines and good construction details that show that the silhouette is intentional. These dresses work because structure creates the shape rather than relying on fit or volume. We look for fabrics that are substantial enough to hold detail work and seaming that is clean. A structured two piece dress is the answer when you want the dress to look designed rather than just put together.
