LOS ANGELES -- Designer Stella McCartney is ready to see the Me Too movement sweeping Hollywood make its way to the runways.

"It's about time the fashion industry spoke up a little more," said McCartney during an interview Tuesday at a Los Angeles concert event showcasing her autumn collection.

"We are nearly 80 per cent women in the company, but I also like men. So I'm a big believer in equality," said the British designer, who wore black to support the sexual misconduct defence initiative Time's Up.

Katy Perry, Christina Aguilera, Emma Roberts, Kate Hudson and Goldie Hawn were among the starry guest list.

"She just gives me the pallet and I paint with it and tonight I'm red!" said Perry while making her way into the party wearing a ruffled, flowy frock.

It was a family affair with Paul McCartney walking the red carpet before performing for the fashionable crowd.

The elder McCartney told reporters he was "super proud" of daughter Stella and joked that she got her sense of style from his former Beatles bandmate, Ringo Starr, who was also in attendance.

McCartney joined the band Muse onstage for Beatles' hits like "I Saw Her Standing There" and "Helter Skelter." Other performers included St. Vincent and Beck featuring the Compton Kidz Club choir.

Models were perched around the event space accentuating the rock concert setting with faded denim, funky animal prints and cozy sweaters. A neon Time's Up sign welcomed guests to Hollywood's S.I.R. Studios.

Sheer French lace showed up on slinky pastel slip dresses, sleeves and tracksuits. Leopard print ran throughout and a cinched-waist jumpsuit mixed red chevron with stripes. McCartney's men's line included preppy polo shirts and V-neck sweaters matched with patterned overcoats and relaxed track pants or jeans.

"It's approachable," said McCartney of the collection. "Naturally confident, naturally sexy and modern."
