The lady was not pleased with Scouts apparels and did not approve them. She wanted Scout to be a lady and cover herself in the same way. she also wanted her to interact with the females.
She wanted the children to learn about their family and their history, and disagreed with their father about the same.
She did not interaction of the children with the non-whites like Walter, and therefore, forbidden Scout and Walter Jr. paying together.
For power and to pay off debts. Hope this helps! :)
