All the Halloween festivities may be done and dusted 'till next year, but all last night's fancy dress action is making our social media feeds worth scrolling through today.

Shanina Shaik channeled her inner Rihanna.
Izabel Goulart went as a UFC fighter.
Kate Grigorieva was a very sultry cat woman.
Stella Maxwell went as a baby. Because, of course.
Josephine Skriver was terrifying as Lilith (a Hebrew term that translates as 'screech owl' - a creepy night demon).
Taylor Marie Hill went as Cleopatra (plus Stella Maxwell and Josephine Skriver changed into next level dead cheerleader and skeleton costumes).
