Stella McCartney once more demonstrated she's the ultimate feel-good designer, delivering Monday a ready-to-wear collection of breezy summer clothes that make looking good easy.

It was drizzling outside, but the catwalk radiated sunshine as models strutted their stuff in casual chic silk shantung suits, A-line denim skirts and off-the shoulder dresses in primary color prints that were begging to mambo.

"For summer, it's not about aggression or power, it's about being positive and being a real woman," McCartney told reporters in a backstage interview. "For me those were real women coming down the runway."

The real women in the packed audience appeared to agree and gave McCartney a whoop of approval as she took a bow.

Her father, former Beatle Paul McCartney - who shared his front row perch with companion Nancy Shevell and actress Gwyneth Paltrow - called the show "parfait", and gave it a thumbs up.

"I loved everything she does. She's my baby," he told reporters, shouting over his own voice singing the 1967 hit "She's Leaving Home."
