Well thanks to the lovely reviews, it's super easy to narrow it down.
According to the critics, the top ten fashion shows from Paris Fashion Week A/W 2012 were:
"Even those in the audience who queried the absence of anything approaching clothes for the everyday surrendered to the forward movement of the stunning technique. As for pushing herself, Burton has tapped a vein of absolute magic. Its spell is irresistible."
"It was impossible not to flash back to John Galliano’s own stream locomotive excursion on the Diorient Express back in 1998 … Galliano was king of Paris fashion then, the ringmaster of the fashion circus. It was also the point when Jacobs tentatively began to treed his own path at Vuitton—commemorated in that exhibition, opening today and juxtaposing Jacobs’ fashion innovation with Vuitton’s travel expertise. Ring any bells? This show represented something bigger than clothes: it was symbolic, after fifteen years, of Marc Jacobs officially assuming the crown. In short, if you didn’t know Marc and Vuitton ruled Paris, you do now."
"It’s going to be a big year for Stella—her involvement with that little thing called the Olympics (she’s the creative director of Adidas’ Team GB collection)—and she’s off to a good start."
"For such a graceful, refined performance that considerably advanced the idea that fashion should be of a power and strength that doesn’t ever resort to cliché, there was an incendiary quality to Rick Owens’s show."
"It was 26-year-old Rousteing’s second turn at Balmain today—his chance to confirm the promise he showed with his first collection at the helm last season. He pulled it off, with honors, in a show that managed to better all the maximalist decoration the house is known for … He also proved that a crystal-decked velvet pant could be worn in that offhand way, even, conceivably for day, with something as ‘down’ as a beige shetland sweater. Karlie Kloss—damn."
COMME DES GARCONS
"In the chiffon trenches, Ms. Kawakubo is the only designer who thinks like an artist, in that she creates fashion that modifies your view of something, be it women or an aspect of culture. … Her latest collection seemed to turn couture, and the fashion world’s obsession with iconic shapes and structure, on its ear. Her opening coats, nipped-waist jackets and dresses were rendered as flat two-dimensional shapes in a polyester felt. Their size reinforced the point; they looked stamped out, like so many handbags, by those mercurial giants of fashion."
–The New York Times
"Ten years of Alber! The birthday boy threw a whopping Lanvin party tonight—true, heartwarming, campy, and calorific fun for a stadium-full of the family of fashion. At least for an hour or two—first, a slam-dunk of a collection, and then a sprawling after-celebration—he magicked up a surreally happy respite from the stressed, snippy, gossip-ridden melee of fashion."
"Haider Ackermann is back in sinuous mode. … The waisted silhouettes that were the results of all that draping were the best he’s ever done—a spot-on mixture of the sublime and the salable, and he’s got the most sophisticated color sense of anyone in Paris."
"As for the clothes: they were nothing short of perfect. Oversized coats in tufted wools and felted cashmeres, equally roomy trousers with a dropped crotch and a moulded, subtly curved silhouette, sweaters that—similarly—stood away from the body, were all intent on cocooning the woman wearing them as opposed to parading her shape and size for all to see."
"If you have been on the fence about Chloé, it’s time to check it out. Ms. Waight Keller showed some terrific clothes, infused with a lightheartedness that most of Paris seems to have ignored. Where to begin? Chloé offered great outfits, like the friendly notion of wearing a cabled cream pullover with a deep red skirt, or a sleeveless dress with white lace on top and a soft black silk skirt, as well as cool separates."
