Seams run at 45-degree angle rather than horizontal or vertical
Typically silk charmeuse, satin, or rayon for maximum movement
Backless construction common; halter neck or thin straps typical
Identifying Authentic Satin
True satin weave: 4+ warp threads float over one weft thread creating sheen
Silk satin: cool to touch, heavy drape; nylon/polyester satin: lighter, less lustrous
1930s: bias-cut charmeuse (lighter satin weave) vs duchess satin (heavier)
Check for snags or pulls — satin snags easily; examine under good lighting
