PARIS - Katy Perry and Kim Kardashian were the queens of the night at Givenchy's star-studded dusk show in Paris, rocking all-black Givenchy outfits side-by-side as Kanye West, also in black, lurked in the back.

The remaining celebrity attendees, actresses Jessica Chastain, Amanda Seyfried and Noomi Rapace just didn't stand a chance.

Other shows were all about creature comforts, with Kenzo treating bleary-eyed guests to coffee and cookies and singer Lorde, who's sold over 17 million records at the tender age of 18, took a moment to relax, shying away from interviews in the new spring sun inside the Grand Palais.

Here are the highlights of fall-winter ready-to-wear 2015 shows:

PERRY AND KARDASHIAN ARE GIVENCHY'S DARK QUEENS

"Black is always elegant. It is the most complete color in the world," said Givenchy's designer Riccardo Tisci.

With that in mind, the Italian-born designer scored a coup - dressing two of the world's most famous women in his own monochrome looks at the fall-winter womenswear show Sunday - the big ticket of the evening.

The newly-blond Kardashian wore a figure-hugging jumpsuit, with black lacing over a very revealing cleavage, hugging and smiling Perry who stayed demure in a loose black lace shawl.

KENZO SAYS LAYERING IS IN

This season's mantra is: pile it all on. We've seen it notably at Lanvin, Dries Van Noten - and now at Kenzo's draped, voluminous and colorful fashion spectacle.

It takes a lot to drag fashionistas out early on a Sunday morning to a venue on the outskirts of the city. But Kenzo rewarded those who did - feeding them tasty delights - and treating them to an incredibly energetic presentation, in which gargantuan rectangular mirrored walls moved behind models in the warehouse venue.

The collection too continued this energy in its vivid splashes of kinetic graphic lines and flashes of contrasting, colored prints.

But fall-winter was all about the layering. Geometric lines featured on layered A-line column dresses, topped off with funky asymmetrical poncho-hoods.

CELINE UNDRESSES

Designer Phoebe Philo riffed on the theme of undoing, undressing and unbuttoning in a highly creative collection that ended up being more chic than provocative. The Celine woman is, after all, no show-off.

Inner pocket straps were exposed on the torso, one in beautiful burnt orange, with its belt flapping down, undone.

A loose and stylish cream minimalist poncho sweater looked like the model was caught trying to take it off, with one arm in and the other out, and the neck-hole skewed to the side. A cream shawl with a russet band was wrapped haphazardly around the body, as if ready to fall off onto the floor.

Half-unbuttoned, loosely-structured floral shirts were accessorized with multiple huge, abstracted fur cuffs - held together by the normally-invisible string that goes inside the coat.

Eighteen-year-old singer Lorde led the VIP pack at Chloe, inside the Grand Palais, where Paris' spring sun beamed through the venue's glass ceiling.

It was a beautiful touch that nicely set off the collection designed by Clare Waight Keller.

It was on-trend menswear and boho looks in vogue this season, with, for the most part, long-line loose flowing silhouettes.

A militaristic long pea coat with huge lapels and gold buttons set the show going, fusing into a sumptuous Sherlock Holmes-style cape coat in gray, a double breasted peaked jacket in gray check wool, or a scooped boyish waistcoat.

The bohemian looks include a long diaphanous silk crepe dress in purple, twinned with a long thin black neck scarf. It was a safe collection with very eclectic proportions.
