The theme I received from bonpon this time was "Block check & clothing that can be worn as a jacket". So I decided to make one-piece that can be worn as a coat and a shirt that can be worn as a jacket. I used a thick fabric made from the thickest thread and tailored it in a design similar to a trench coat. The round collar was a special feature of pon. The bottom half of the waist is finished with a hidden placket, so that when worn as one-piece, it looks like a pullover. I created one-piece that can be worn on its own or as a jacket, and can be enjoyed in two different ways.
