The garment in question is a short, upper-body covering featuring a distinctive, mottled appearance achieved through a specific chemical treatment. This process involves the use of chlorine or similar agents to partially bleach the fabric, creating a high-contrast, textured visual effect. A common application of this aesthetic is found in conjunction with a truncated shirt or blouse.
The popularity of this style stems from its association with certain subcultures and fashion trends, particularly those of the 1980s and 1990s. The bleached effect lends a rebellious or alternative edge to the garment, while the abbreviated length offers a modern, youthful silhouette. Historically, this type of surface treatment provided a cost-effective way to update existing clothing, adding visual interest and extending the lifespan of garments.
