What describes one-of-a-kind garments created by designers?

One-of-a-kind garments created by designers are best described as "designer" pieces. Designer clothing typically represents a high level of craftsmanship and creativity, often featuring unique elements or exclusive designs that set them apart from mass-produced items. These garments are usually made by well-known fashion designers or brands that emphasize artistry and a personal touch in their work, catering to a clientele looking for unique and exceptional fashion items.

In contrast, limited edition items imply that a small quantity is produced, but they are not necessarily one-of-a-kind. Custom made refers to garments tailored to an individual's specific measurements and preferences, which might include elements from the designer’s collection but are distinct from the designer creations that are meant to stand alone. Fast fashion describes garments that are produced quickly and at a low cost to capitalize on the latest trends, differing significantly in quality and exclusivity compared to designer pieces.
