Garments worn during the Halloween season that are intentionally revealing or transparent fall under the umbrella of suggestive costuming. These outfits often incorporate sheer fabrics or designs that expose significant portions of the body. For example, a ghost costume made of very thin, gauzy material that reveals undergarments would be considered suggestive.
The prevalence of such apparel reflects evolving cultural attitudes towards self-expression and body image. Historically, Halloween costumes have ranged from the frightening and grotesque to the playful and whimsical. The recent emergence and acceptance of more revealing options highlights a shift towards embracing sensuality within the context of festive celebrations.
