While they both donned elegant black attire, Kate donned a midi-length dress with an asymmetrical halterneck, while Mia stunned in a sweeping jumpsuit featuring a deep V-neckline and a striking white waistline.
This mother-daughter duo previously shared the screen in Channel 4's "I Am Ruth," where they portrayed an on-screen mother-daughter pair.
