The Crown star wore a stylish and trendy red dress with puffy sleeves, which she paired with a matching clutch and pointed heels. But did you catch what she was wearing on her right hand?
Olivia had adapted a badge, which she wears wearing as a giant ring on her middle finger. It read, "Equal representation for actresses, 50:50."
ERA 50:50 is a British organization that wants gender balance on stage and screen in the UK. According to its website, it was started after a report revealed male actors are overrepresented in Britain by a ratio of 2:1 and crowd scenes are just 17 per cent women.
