It shows that Mrs. Flowers thought ahead by considering not only children's behavior in general--"Children these days would bust out of sheet-metal clothes. They so rough."--but also what Mrs. Henderson would expect to avoid problems with the dress. Because of her awareness of others' feelings, she knew what to do before she was even asked.
The dialect used in "Woo'd and Married and A" adds to the intensity of the mother's emotions about the subject.
All powerful, ‘God’ is commonly described this way. :))
