This is a YZEEY GAP ENGINEERED by BALENCIAGA T-shirt. It's commonly known as the "Pigeon T-shirt." It has a mock neck, giving it more presence than a regular T-shirt, and the fabric feels very high-quality. I purchased it in line at PLUG in Osaka (receipt and shopping bag available if needed). It has a Kanye silhouette, with a shoulder width of 67cm and a length of 74cm (approximate measurements). It's quite oversized, so most people should be fine with an XS. It is guaranteed authentic, so please feel assured. I've worn it a few times. There are no noticeable scratches or stains, but please refrain from purchasing if you are overly sensitive. Thank you for looking. Yeezy Gap Balenciaga
