The British models, who helped launch Burberry's new store in Shanghai this month, have given tips to wannabe catwalk stars on how to prepare for shows and insist a model should never take to the runway on an empty stomach.
Cara told E! News: ''Drink a lot of water, and make sure you've eaten enough. And know where you're walking. That's always a hard one.''
Suki, 22, who is dating Hollywood actor Bradley Cooper, added: ''Vitamin C and the hardcore stretching ... always workout.''
The pair agreed one of their favourite parts of the Shanghai trip was listening to singer Paloma Faith, who performed during the Burberry show.
Cara, 21, also enjoyed being hooked up to ropes as she flew through the air Mary Poppins-style while carrying a Burberry umbrella during the theatrical show.
Meanwhile, back on British soil the best friends enjoyed a night out on the town on Saturday night (26.04.14) with fellow model Georgia May Jagger in west London.
The trio were photographed running across a street and pulling funny faces for the paparazzi as they enjoyed a girls' night out.
