This piece is new old stock. It has never been worn or washed. While the vintage label states EU 48-50, please refer to the flat-lay measurements below to ensure a good fit, as vintage sizing differs from modern high-street brands. Pit-to-Pit: 24 inches (Approx. 48" chest) Estimated Modern Fit: UK 18 (Oversized/Relaxed) or UK 20 (Standard Fit) This piece has thick sewn in shoulder pads, and a slight faint mark near the anchor which will wash out but as this is NOS I didn't want to wash it.
