They've regularly opened up about their veganism and campaigning for animal rights.

And Made In Chelsea sisters Lucy and Tiffany Watson both put on a stylish display to attend the launch of their new vegan restaurant called Tell Your Friends in Chelsea, London, on Thursday evening. 

Lucy, 27, showed off her slender figure in a light blue sheer crocheted shirt with ruffles on the front and black bows on the wrists.

The reality star, who is smitten with MIC boyfriend James Dunmore, teamed the ensemble with a pair of navy trousers with a tie waist, which subtly showed off her flat stomach. 

Accessorising her look, Lucy added a set of patent black heeled mules and a clear clutch bag with a white pattern on it. 

She styled her dark brunette locks into a curly tousled hairdo, which swept to the side.
