This picture is of Aunt Lena in the 1940's. She was always the best dressed and most stylish.
Here is the addition that Mary Lynn wrote when she edited the book.
Here is how the paragraph was changed by me.
When they arrived at Seitner's they ran into Isabella's Aunt Lena selling coats. They had climbed the stairs to the second floor to see the formal clothes. Aunt Lena was at the top of the stairs with a customer. She waved at the girls, but they knew from past experience not to interrupt Aunt Lena when she was with a customer. Isabella's grandmother had told her many times, "My sister, Lena, can sell a coat better than any other salesperson." Isabella knew that her Aunt Lena had worked at Seitner's forever. None of the sales clerks at the store knew that her Aunt Lena was ninety years old! The store owner wasn't even sure how old his best sales person was, because she had been hired by his father. They all guessed that she was in her seventies. All he knew for sure was that she could outsell every other sales clerk on the floor.
