LONDON (AP) — London Fashion Week moved into high international gear Saturday with a debut collection from Barbadian pop diva Rihanna, a Native American-inspired show by Brazilian-born Issa and a host of other eclectic offerings.

No one went to Rihanna’s Saturday night debut as a fashion designer expecting demure dresses set off with tasteful pearls.

So no one was surprised by the double-volume hip-hop music, smoke machines and champagne that greeted guests at the unveiling of her Rihanna for River Island collection.

And few were taken aback by the bad girl, rock chick styling of some of her clothes, with tight-fitting jersey outfits and dresses cut to show more than a bit of leg.

It was a fun, flattering collection aimed at young women, containing nothing shocking or outrageous from a singer who has been known to bring those elements to her live performances.

She provided some pop star glamour to an already glittering London Fashion Week, which will soon showcase the work of Vivienne Westwood, Burberry’s Christopher Bailey, and Tom Ford.

Rihanna followed Brazilian-born Daniela Issa Helayel (better known as Issa), John Rocha, Julien Macdonald and others to center stage on the second day of fashion week.
