Rocking a 1950s inspired look, the RiRi looked like an extra from Grease in the baby pink ensemble.
Choosing a cute flared mini-dress - tied around the waist - the star was able to perfectly show off her slender legs.
She teamed the flirty look with vintage style pink glasses and a matching handbag.
Pink appears to be a recurring theme for Fashion Week. Rihanna also rocked the colour at Christian Dior's show, which she attended with her mother Monica Braithwaite and Rajad Fenty.
