Paris - A relaxed Gwyneth Paltrow looked very much the part as she arrived at Chanel's celebrity-filled "atmosphere of calm" eco-show inside Paris' Grand Palais.
Here are the highlights of Tuesday's spring-summer 2016 couture collections.
CHANEL'S CELEBRITY MOOD GARDEN
A huge "mood" garden decor, replete with a relaxation pond, forest and grass, greeted the 43-year-old Oscar-winner Paltrow, who posed for cameras in a check Chanel skirt suit with high collar near some steps leading up to a minimalist wooden hut.
It was so realistic there was even a small swarm of flies buzzing around on the verdant lawn.
Paltrow, who curates healthy lifestyle publication "Goop," looked around in awe, clearly approving of Chanel designer Karl Lagerfeld's new-found green musing.
Other celebrity attendees included actresses Monica Bellucci and Diane Kruger.
CHANEL GOES ECOLOGICAL (KIND OF)
Couture is not the industry most readily associated with ecology. But if it's up to Lagerfeld, whose latest passion is the garden, things may well be about to change.
Aside from the show decor, the 75 Chanel looks featured jewelry and embroideries made from wood shavings and straw.
They were, of course, given a Chanel-style makeover: fastidiously painted, treated and molded by the atelier into exquisite shapes and paillettes that resembled white feathers and flower petals.
"Ecology is something that's never been used in high luxury before. But I found these materials quite pretty if used in the right way," explained the couturier.
He didn't miss the opportunity to point out that this display is a first, as most eco-fighters "don't take care of their appearance."
CHANEL GETS CURVY FOR SPRING
It was a strong, delicate and sports-infused collection for spring.
Smooth oval shoulders and curved collars defined the silhouette on fastidiously embroidered gowns and skirt suits.
The curved aesthetic, which was apparent also in oversize bulbous chignons, curved cork platforms and usual double-eye makeup, was inspired by the 1932 cubist sculpture "Head of a Woman" by Pablo Picasso.
But this was very much a contemporary collection with assorted iPhone pockets hanging loosely from the models' waists.
The evening-wear got more enchanted, with strapless dresses or pants with a train complemented by painted capes with rhinestones, wide-cut boleros or embroidered jackets.
There were fairy-like touches, like a pale pink silk gown, with Tinkerbell-like zigzags cut into a tiered skirt and large diaphanous cuffs. A glimmering cape on model-of-the-minute Gigi Hadid also added to the magical vibe.
