Well, I can understand how you feel. My kid is also doing the same thing as soon as he is diagnosed with ADHD. I replace all clothes with his favorite cartoon character shirts and jeans of his own choice. Now, he wears his clothes in no time as he enjoys wearing them. You can also do the same. This might help you out with your situation. You can explore Reecoupons, they have exciting collections of kids clothes. I am sure your kid will like to wear them.
