Deconstructed clothes, blown-up prints, and dizzying pattern contrasts shook up the VIP-filled runways at Paris Fashion Week.Lanvin, Maison Margiela and Dries Van Noten were among those showing previews for the fall-winter 2017 shows.There's been a dramatic change in tone at Lanvin since Bouchra Jarrar took over the creative reins from Alber Elbaz last year.Slim-cut jackets, menswear python chain boots, and - gasp - pant suits have all been injected into the house's nostalgic DNA of uber-feminine, diaphanous and glitzy gowns.The Maison Margiela designer took to the classic wardrobe with couture scissors for an inventive show that pared down garments to their bare essentials. The opening look - a traditional stone trench coat - was cut away at the chest into a heart shape to evoke the silhouette of a bustier dress.Belgian designer Dries Van Noten, a lover of flowers and of Eastern styles, fused both passions together in the show Wednesday - resulting in a contrasting fashion symphony of color and kinesis.And this was all served up on the designer's signature oversize and loose silhouettes.A voluminous coat with a red rose motif was optically overlaid with Asian-looking geometric circles. Elsewhere, thin stripes that evoked the material of a Japanese kimono were punctuated with bright blue semicircles, and capped off with contemporary blue denim jeans.Asiatic satin sheens shimmered past guests.And it this weren't enough, luxuriant colored fur trim was thrown in - onto coat lapels and sleeves - to ensure that this collection was one of the most vibrant seen so far this season.Celebrating designer Anthony Vaccarello's sophomore outing for Saint Laurent, the Kering-owned fashion house hosted a glitzy celebrity-filled soiree that ran into the early hours Wednesday following the collection.Model Eva Herzigova, 43, and actress Zoe Kravitz, 28, led in the glamour stakes wearing outfits with plunging necklines to the Le cabaret Paradis Latin venue.Other VIPs in attendance included Jane Birkin's daughter Lou Doillon and filmmaker Gaspar Noe, who all were treated to a live performance by French band "Rendez-Vous" amid the venue's metal and neon installations.
