This provocative cosplay costume set, labeled '654制服' (654 Uniform), features a stylized nun-inspired design with bold erotic elements. The ensemble includes a black satin-like mini dress with deep side slits, sheer long sleeves, and decorative white crosses at hem and chest; a detachable white wimple-style collar with black cross accents; a matching black headpiece (头纱); and black thigh-high stockings with garter straps. The most distinctive feature is the large black heart-shaped cutouts over the bust area, revealing skin while maintaining a theatrical silhouette. Made from smooth, stretchy synthetic fabric for form-fitting wear, it prioritizes visual impact over modesty. Ideal for adult-themed photo shoots, Halloween parties, or roleplay events—strictly not religious attire. The set is marketed as a complete four-piece outfit (headpiece, dress, capelet/collar, T-pants/stockings). Due to its explicit design, it is intended for mature audiences only and should be worn with discretion in appropriate private settings.
