extended information
when buying clothes, under careful observation, most of the inner layers of clothes are labeled with different numbers, letters and symbols. According to experts, in China, lean body type is generally represented by Y, and A, B and C represent normal, overweight and obese respectively. The specific size of the jacket is marked as: 165/88A, which means it is suitable for people with a height of 165 cm, a bust of 88 cm and a body shape.
At the same time, there are other information in the instructions for the label inside clothes. For example, the wavy line in the basin is the basic washing symbol, and inserting a hand indicates that it can be washed by hand. The iron graphic indicates ironing, and a cross on it indicates that it cannot be ironed. Pay attention to the safety level label on the inner label.
Class A can be worn by infants under 2 years old; Class b is a product that can contact the skin; Class C is a product that cannot directly contact the skin. If you find underwear marked as Class C or "Qualified", don't buy it. (China Trademark Inquiry Center)
