Black is sexy! Most of the Bollywood babes still believe in this old saying and is the safest colour to opt for. Following it is 'Befikre' actress Vaani Kapoor. She undoubtedly has an amazing physique, which is quite evitable in all her photos. Although, we don't see gym pictures of Vaani circulating on social media every day but the actress has surely worked hard to get the hourglass figure she is living in.
