This is a Bonum 2-way cardigan. The size is free. The sleeves can be removed to be worn as a sleeveless top. The vibrant orange color and the design with different knitting widths on the left and right sides are stylish. The thin and smooth fabric is recommended for a light outer layer in hot weather or for protection against air conditioning. It goes well with various bottoms such as denim, cargo pants, and chinos. There is a faint black stain (as shown in the last photo) between the first and second buttons, which has been there since the time of purchase. If you are interested, please take a look at the profile before purchasing.
