Tina Knowles, American fashion designer, founded House of Deréon

Celestine Ann "Tina" Beyoncé Knowles is an American businesswoman, fashion designer, author, and philanthropist known for establishing the brands House of Deréon and Miss Tina by Tina Knowles. She is the mother of singers Beyoncé and Solange Knowles and was married until 2011 to their father Mathew Knowles, the manager of Destiny's Child. For her contribution to the fashion business, Knowles was honored at the Accessories Council Excellence Awards in 2001.

House of Deréon was a ready-to-wear fashion line introduced by singer and actress Beyoncé and her mother and then-stylist Tina Knowles. The style and concept was inspired by three generations of women in their family, with the name "Deréon" paying tribute to Beyoncé's maternal grandmother, Agnèz Deréon. House of Deréon discontinued its junior line in 2012, and was unofficially discontinued in the following years.
