This men's Chinese vintage - inspired summer streetwear set is perfect for casual outings. To wear it, simply button up the single - breasted shirt and fasten the button fly on the pants. When choosing a size, always refer to the size chart because different suppliers may have different sizing standards. If it's Asian sizing, go for a bigger size. For maintenance, this polyester set can be machine - washed in cold water. Avoid using bleach to keep the color and fabric in good condition. Hang it to dry to prevent any shrinkage. With its notched collar, half - sleeves, and solid pattern, this set is both stylish and easy to take care of.
