"Swish" can describe something stylish and elegant, similar to "chic" or "posh," but it can also describe a smooth, rustling sound. Think of a well-dressed person gliding through a room or the sound of silk fabric moving. It suggests a sense of effortless grace and sophistication. It can also imply a flamboyant or exaggerated style. It also describes a sound, so the context really matters. It implies being well-to-do.
