Let's face it: Anna Sui knows how to have fun. So much fun, in fact, that we were even treated to models like Lily Donaldson, Joan Smalls, and Lindsey Wixson smiling on the runway! For Fall '12, Anna drew inspiration from a 1960s Jean Shrimpton silhouette but, in Sui style, took care to put her own signature whimsical spin on it, as seen in the psychedelic patterns and color palette. While the super-textured shag coats, Woodstock-worthy caftans, and babydoll dresses certainly set the retro tone, it was the designer's attention to the owl motif that left a lasting impression. The knitted owl hats, owl-shaped sunglasses, and owl-embellished fingerless gloves were just a few of the not-so-subtle themed items found within this playful lineup. Also worth noting? Anna Sui collaborated with Coach to design this season's line of bags — newly debuted on the runway — and yes, they had owls on them, too. It was a total Anna production, just youthful and fun from start to finish.

• Trends: Owls, oversized Peter Pan collars, super-textured shag coats, '60s-style babydoll dresses, and bright tights.
• Colors: Rich autumnal colors — rust, orange, ecru — matched up with neon blue, fuchsia, and pink.
• Key Piece: The cozy shag coats over sweet babydoll dresses.
• Accessories: Newly debuted line of Anna Sui for Coach bags, knit owl hats, owl-shaped sunglasses, knit fingerless owl-embellished gloves, and neon tights.
• Who Would Wear It: Fashionistas with a taste for kitsch and color, like Hailee Steinfeld and Chloe Moretz.

The ethereal collection of Marchesa gowns shown for Fall 2012 left us with one question: which A-list celeb will wear which dress on which red carpet? One by one, models floated out in decadent floral appliqué bodices in golds, crimson reds, and aquamarine teals, complete with even more ornate tulle-enhanced skirts, fit-and-flare silhouettes, and sheer formfitted overlays. Marchesa dresses are more about fantasy than anything else, and these dresses had a romantic feel, as if they had been plucked from the bodies of different heroines in Edwardian-era novels. There were looks for a princess in the full-skirted ball gowns, sheer lace dresses with asymmetric hems that would belong to the sexy mistress, and the queen who leads her country into battle — we can't think of a better look than the short black leather dress with black knee-high gladiator sandals.

• Trends: lace embroidery, feathers, gold detailing, lace
• Colors: red, gold, cream, black, baby blue
• Key Piece: a red embroidered dress with a huge skirt was a showstopper, and we love the short, light cocktail dresses.
• Accessories: luxe gladiator sandals and delicate pointy-toe heels.
• Who Would Wear It: Blake Lively will wear the short cocktail dresses all year, and Marchesa fans like Lea Michele, Halle Berry, and Jessica Biel will all give these dresses a spin on the red carpet.

Michelle Smith showed a fun collection brimming with color and cool techno fabrics for Milly's Fall line. The results? A prim and polished collection injected with modern fabrics and a bit of edge. Tweed dresses were given a shiny finish thanks to a high-tech laminated finish, while full leather skirts lent a feminine feel. A wide array of cocktail-ready dresses were the main focus, ranging from scalloped hemlines to strapless neon and lace confections. Standout pieces included a brilliant metallic purple skirt paired with a textured dotted jacket and a red patent leather funnel-neck coat. More details from Milly's ladylike cool collection below.

• Trends: Techno fabrics, embellished collars, full skirts.
• Colors: Cobalt, green, black, hot pink, chartreuse, purple, red.
• Key Piece: The laminated tweed dresses were simultaneously fresh and feminine.
• Accessories: Shearling clutches, satchel bags, opera gloves.
• Who Would Wear It: In addition to front row attendees Tinsley Mortimer and Kristin Chenoweth, we can also envision Upper East Side personalities, like Blair Waldorf, wearing some of these pieces.
