Can you help me rephrase first part of the song "Parents just don't understand",please? Thank you very, very much in advance

1) Parents just don't understand that children are going to make mistakes.
2) The song says that once a mother took his child (the singer?) school shopping with his brother and his little sister.
2) They headed to the centre of town to a large shopping mall.
3) At first, his mother started bugging with clothes she chose (how can I rephrase it?)
4) The singer (?) didn't say anything. He just turned up his nose.
5) She wanted to buy him a shirt which cost only 20$. He replied he didn't like it because it was plaid with a butterfly collar.
6) Then she did the ultimate (how can I rephrase it?) when he asked her for Adidad and she bought him Zipps. He wanted her to put back the clothes because they (?) were going to ruin his reputation (??).
7) His mother replied he was going to school to learn and not for a fashion show. (?)

2. A mother took HIS child? Confusing at best. Is this the grandmother with a son's child?

3. started "pushing" clothes she chose?

6. it was the "last straw?"

This is a song? What song? If I could see the song, I'd know better what you are trying to say.
