how does aunt alexandra's verson of a lady differ from scout's verson?

From the text:

"Aunt Alexandra was fanatical on the subject of my attire. I could not possibly hope to be a lady if I wore breeches; when I said I could do nothing in a dress, she said I wasn't supposed to be doing things that required pants. Aunt Alexandra's vision of my deportment involved playing with small stoves, tea sets, and wearing the Add-A-Pearl necklace she gave me when I was born; furthermore, I should be a ray of sunshine in my father's lonely life."

In contrast, Scout prefers to be a tom-boy. She wants to play with the boys, get dirty, fight, and swear when it suits her. Their definitions of being a lady couldn't have been any more different.
