I want to know the answer to the following question:
What was the name of the junior fashions launched in 2009 by Beyoncé and her mother?
All the background I'm provided with is that "In July 2009, Beyoncé and her mother launched a new junior apparel label, Sasha Fierce for Deréon, for back-to-school selling.". Is that enough to answer the question?
Answer: yes
