Kiko Kostadinov's Petrel sweatshirt reimagines contemporary knitwear through architectural proportions and textile manipulation. Cut from soft cotton piqué jersey, the design features a sculptural draped hood that wraps scarf-like around the shoulders, while articulated sleeves are traced with contrasting cover-stitch stitching that follows the garment's anatomical lines. A front placket in smooth fabric and side tabs with button adjustments complete the deconstructed silhouette, balancing relaxed volume with precise construction details that emphasize the piece's innovative design.
