Katie Holmes is the latest fashion-conscious celebrity to be taken with Charlotte Olympia's ever-popular Kitty flats.
We spotted the actress looking super stylish, channelling a subtle 50s Audrey Hepburn vibe in Berlin's Tegen airport wearing a dark belted trench, blue ankle-grazers and the black velvet slippers so loved by the fash pack.
And the mother-of-one make sure that everyone got a look at her feline flats, deciding to swap out of a pair of on-trend Adidas Stan Smiths to don the velvet slip ons as she headed out of the airport.
Charlotte Olympia's Kitty flats have become a modern day wardrobe staple ever since they launched in 2011. Alexa Chung, Kirsten Dunst and Sarah Jessica Parker are all still wearing theirs – and we don't think we're going to see the back of those whiskers anytime soon.
