We’ve noticed two celebrity style trends this week: rich ruby reds and plums (here’s looking at you Naomi Campbell and Katy Perry), and plenty of chic black and white. Which style trend is your favourite?


Naomi Campbell looked regal in a rich plum Zac Posen gown with billowing cape at a photocall in Sydney for The Face Australia.


Seems like rich reds are the colour du jour, with Katy Perry wearing a luxurious ruby red gown and cape at the UNICEF Snowflake Ball in NYC (where she was bestowed a humanitarian award).


Angie Harmon also looked incredibly glamorous at the UNICEF Snowflake Ball, flashing a little side boob in her black and white Angel Sanchez gown.


Also at the UNICEF Snowflake Ball, Christina Ricci in a sexy Carolina Herrara off-the-shoulder gown with cheetah-print skirt.


Julianna Margulies channeled Audrey Hepburn in monochrome chic at a fundraiser for paediatric AIDS in New York.


Marion Cotillard always has incredible celebrity style, here in a striped Dior dress with strappy sandals at the Marrakech Film Festival, accompanied by Martin Scorcese…


…Another day, another stunning Dior gown.


If Keira Knightley’s dress looks familiar – it should! It’s her Chanel wedding dress recycled for Tuesday’s SeriousFun Children’s Network gala in London. More celebrity dress recycling, please!
