Check out her lipstick.
As we all know, the film is set in 1912, the year of the Titanic accident. Rose’s rich status meant she wouldn’t have worn the iconic red lipstick worn by Kate Winslet in the film at the time. She probably wouldn’t have put on any makeup at all.
In England at the period, wearing cosmetics was connected with suffragettes and lower-class females without a “proper” upbringing. Kate, on the other hand, looks really lovely in that lipstick.
