A striking black tailcoat with bold gold piping and button accents, designed in a modernized燕尾服 (swallowtail) silhouette—featuring a high collar, double-breasted front with brass-toned buttons, and dramatic asymmetrical rear tails. The gold trim runs vertically along lapels, pocket edges, and sleeve cuffs, adding luxurious contrast and visual dynamism. Constructed from structured yet flexible fabric for tailored drape without stiffness, it offers both theatrical flair and wearable elegance. Ideal for cosplay, stage performances, gothic/steampunk fashion events, or avant-garde formal occasions. Lightweight at only 0.36kg (S size), it balances drama with comfort. The inner lining appears smooth, and the garment maintains sharp lines when worn open or closed. While labeled '燕尾服' (Chinese for tailcoat), its styling diverges from traditional formal wear—leaning into alternative fashion with punk, Victorian revival, and cyber-goth influences. No visible brand logos or tags in images; likely an independent designer or generic costume piece.
