London, UK - Rihanna declared that bathrobes are in with a trendy new look for her Fenty Hair launch!

The 36-year-old Fenty mogul just launched another cozy fashion trend that's perfect for comfort seekers everywhere!

Earlier this week, RiRi pulled up for the end of London Fashion Week to celebrate the launch of Fenty Hair at the British department store Selfridges in a butter yellow, furry Jacquemus coat.

She added matching satin pumps, a diamond-encrusted anklet, and jeweled drop earrings to the cozy wear as she wore her hair in luscious and loose dark waves.

Later, RiRi upped the ante with a second fit that was a vintage, butter-yellow John Galliano dress that featured sheer ruffles all over, complete with a plunging neckline.

The Diamonds hitmaker paired that dress with metallic high-heeled sandals and a bold red lip.

Rihanna announced her Fenty Hair line back in June via Instagram, writing, "I am launching a flexible line of products for not only every hair want, but every single product is designed to strengthen and repair all types of hair, which is what we truly need!"
