With gray sweatpants, you should pay attention to two points:
First, gray itself is relatively low-key and dim, so don't wear a gray shirt, which will make you feel disgraced and dusty;
Second, gray sweatpants should not be matched with pure gray sneakers. Of course, leather shoes are even more unreliable. Usually sweatpants can only be paired with sports shoes or casual shoes. Hiking shoes can depend on the situation. In short, it can't be the same color from head to toe, and gray is more important.
For children's shoes that like to wear gray sweatpants, we can use white or light yellow T-shirts or even soft colors like pink. Girls can choose from a wide range, they can wear more conventional clothes, and they can also wear more playful and lovely clothes. Boys can choose simple black or white T-shirts to highlight their athletic temperament. It's best not to try shirts or something, which are not suitable under normal circumstances. In addition to the precautions for matching gray sweatpants, other aspects may need to be observed by yourself. In short, what makes everyone satisfied is right.
