How should fabrics be selected for light layering activewear?

Fabrics should be selected by layer role. Base pieces need soft handfeel, stretch, and recovery against the skin. Support pieces such as leggings or structured bras need opacity, compression balance, and shape retention. Light outer layers need enough coverage without feeling bulky. If every fabric is too heavy, the capsule feels overbuilt. If every fabric is too light, the collection may lose structure and premium feel.
