To where the charity children play.
I want a good time today.
They do some wonderful things.
They have some wonderful fun.
My mother sneers, but I say it's fine
How they don't have to go in at quarter to nine.
My mother, she tells me that Johnnie Mae
Will grow up to be a bad woman.
That George'll be taken to Jail soon or late
(On account of last winter he sold our back gate).
But I say it's fine. Honest, I do.
And I'd like to be a bad woman, too,
And wear the brave stockings of night-black lace
And strut down the streets with paint on my face.
Presumably the “strut,” black stockings, and “paint” indicate that Johnnie Mae is a young prostitute. The speaker thinks living that life wouldn’t be so bad, as she’s had a sheltered life and would like to experience the other side. 
 Brooks dresses the “bad woman”; she gives her a dress code based on the dress code prescribed by the front yard.  Brooks also gives the dress code an adjective “brave.” This is reminiscent of 3rd wave feminism, which was an intense push to appropriate  words like “bitch” and stereotypes like the “bad woman” in an attempt to defy the patriarchal system.
