This is a size 150 check shirt. I bought it at Uniqlo. I bought it for when I wear shirts, etc., but I rarely had the opportunity to wear it and it's now too small, so I think I wore it 1-2 times. The base color is dark navy, which makes it easy to match with various outfits. It's 100% cotton and can be worn for a long season, except for summer♪ Pattern/Design...Check Season...Winter, Autumn
