Rihanna headlines NY Fashion Week day four

Barbadian superstar Rihanna brought much needed oomph to New York Fashion Week Sunday, with motorcycle stunt riders soaring over giant pink sand dunes in her latest fashion collaboration for Puma.

After spending the last two season in Paris, the 29-year-old hitmaker brought her spring 2018 collection back to the US cultural capital in a look more sporty than ever, waving and blowing kisses to her fans at the end from the back of a motorcycle, arm around a helmeted driver.

Her models paraded in whites, pinks and electric blues down a catwalk with glistening pink sand dunes in the background -- donning clinging catsuits, body suits, swimwear, cycling shorts and sharp anoraks.

In what was her fourth Fenty x Puma collection, the emphasis was on serious sportswear with striking technicality, different cuts, use of material and propensity for pockets.

Hunky male models strode shirtless, showing off rippling abs. Razzmatazz came from her motorbike stunt riders jumping off a ramp, soaring nearly 40 feet (10 meters) into the air to open and close the show.
