Therewas a retro feel to the proceedings at Marc Jacobs' Louis Vuitton showeven before the first model strolled around the splashing circularfountain.

It's been freezing in Paris for the past week, and looking at the gray knit leggings Vanessa Bruno paired with almost everything on her runway made me wish I were wearing them right now.

The deep freeze started last night at the YSL show held in the Grand Palais, the same venue that hosted this morning's Chanel extravaganza. The chilled-to-the-bone audience attributed the sub-zero temperature to the weather outside and to the not-at-all insulated beaux arts building. However, upon taking our seats at Chanel, we learned that the meat locker conditions were attributable to the iceberg (in another part of the building and unseen last night) that needed to be maintained as the centerpiece for what was about to be Karl Lagerfeld's arctic expedition.

Of all of the trends we see recycled season after season, here's one that doesn't pop up often: nun-chic. But that was the message on the Yves Saint Laurent runway.

'50s, '80s, 2010, tribal, biker, glam... Pick any one, and you'll find a piece in Isabel Marant's fall collection that fits the trend.

We were absolutely transported by the romantic, feminine fare at Nina Ricci: Bouquet-worthyfloral appliques, bustled pencil skirts, rich satin slip dresses, andnipped-at-the-waist, ladylike skirt suits.

Whileit hasn't exactly been a back-to-basics fashion show season, there seems to be an emphasis on craftsmanship, quality, and designersreconnecting with the spirit of the clothes that originally put them on the map. And this was exactly the case at Dolce& Gabbana.
