The only exception to this seems to be Jennifer Aniston, yet literally you never see older white actresses considered hot anymore. It seems once they hit they're 30's they are given the cold shoulder. Meagan Fox, Lindsey Lohan, Anne Hathaway, Amanda Seyfried, Emily Blunt, Rachel McAdams, Angelina Jolie, etc...
Now all the 'hot" white actresses are young. Emma Watson, Jennifer Lawrence, Emma Stone, Margot Robbie, Emma Roberts, Blake Lively, Ashley Benson etc... All of them are under 30 are considered the hottest now.
Yet actresses who are women of color, literally all of the hottest ones of today who are getting the roles are much older
Kerry Washington (39)
Sofia Vergara (44)
Taraji p. Henson (46)
Gabrielle Union (44)
Regina Hall (46)
Tika Sumpter (36)
J. Lo (47)Paula Patton (41)
Stacey Dash (49)
Why after a certain age are white actresses sort of brushed aside? But actresses of color are continuously seen as the hottest in their group and still given many roles even when they're in their 40's.
