As Day 4 of New York Fashion Week ended Sunday (Sept. 11), the distinct neon glow and sporty silhouettes that have been threading through the tents so far showed no signs of stopping. Almost every collection of the day incorporated the loud neon to their athletic inspired items. From Gwen Stefani's androgynous spring creations to Victoria Beckham wondering if she should change from Posh Spice to Sporty, Spring 2012 is all about a relaxed yet chic athleticism.
L.A.M.B Spring 2012
VIBE: Seeking inspiration from the Rat Pack, high voltage, and Maharaja, Gwen created a spring line that matched the singer's relaxed eclectic and tomboyish look. Slouchy jumpsuits, direct black leather jackets, and pop-inducing heels all seemed to have walked straight out of the singer's personal closet. Although Ms. Stefani was a no-show, due to the fact she is finishing up her latest album with No Doubt, her presence could not have been stronger as every look was dripping with her style.

HOT ITEM: A dapper suit colored in spellbinding black and white created a treat.
DESIGNER SOUND: The blended beats during the show were curated by Jeremy Healy, who created a blended cocktail of reggae, African pop, and hip-hop for the presentation.
Y-3 Spring 2012
VIBE: Inspired by British style and Olympic sport, designer Yohji Yamamoto created a sporty London-town spring look. Graphic mod-era prints and box-cut black sweaters and dresses strutted down the catwalk creating a new age punk look. "To me, London style is a funky elegance," explained Mr. Yamamoto. "It's not just downtown. It's not just punk. It's also polished. We tried to capture that." The front row shimmered with glittering guests including Dwight Howard, Samuel L. Jackson, Michael Pitt, and Peaches Geldof.
HOT ITEM: A leather vest with a tulle back created an intriguing hard vs. soft dynamic and highlighted the labels funky elegant attitude.
DESIGNER SOUND: A mixed soundtrack of Tokio Hotel and Miyavi shook up the runway, accentuating the collection's modern grunge aesthetic.
Simon Spurr Spring 2012
VIBE: After consulting on Tommy Hilfiger's spring collection, Spurr shifted focus to his own label at yesterdays show. The Hook caught up with him backstage to chat about his inspirations for both the collection and soundtrack.

"I loved working with the fabric of this collection," Spurr told us. "I was taught by Calvin and Ralph Lauren to push my own boundaries. I wanted to create a sense of familiarity with this line."
Spurr told us about the importance of music to his collection and how he chooses his runway's soundtrack.
"When I first see the collection all together is when I choose the soundtrack for the runway," he explained. "It unfortunately doesn't always work out the way you want it. This season we are deputing two songs that have not yet been released along with the Rapture. I think people are really starting to look at us for what's new and great in music as well as fashion."
I also caught up backstage with New York Knicks superstar Carmelo Anthony, who couldn't have been more excited. "I love fashion week! I have been to the Tommy show, Rag and Bone and now Simons."
While runway-side, Anthony told me he's been paying "more attention to the clothes," rather than bobbing his head to the music. "But my favorite song right now is Otis by Jay Z and Kanye," he added. Good choice, Melo! He later look a seat front row for the show next to "Gossip Girl" star Ed Westwick, and Cobra Starship singer, Gabe Saporta.
HOT ITEM: The visceral tailoring of the suits designed with contrasting black and gunmetal grey strips of material created a dizzying treat for the eyes.
DESIGNER SOUND: "Miss You," The Rapture, New tracks by the Envy Corps and One Walk On The Beach.
Victoria Beckham Spring 2012
VIBE: Although yesterday was Victoria Beckham's first runway show, the singer/fashion icon has been flexing her style muscle since donning the title Posh Spice. Sixties-looking hourglass dresses ran rampant on the catwalk as Beckham created a modern, sporty Californian look with touches of glamour. Bold straps at the shoulders, strong color blocking, and mechanical looking zippers revealed a clear athletic influence from her dazzling soccer-star husband. Has Posh Spice turned Sporty?
HOT ITEM: A gorgeous soft lilac colored satin jacket added a heightened sense of romance and glamour to the otherwise relaxed and bold collection.
Diane von Furstenberg Spring 2012
VIBE: "The light appears and everything changes," was the message of DVF's Spring 2012 show as the designer handed out small American flags to people, redefining September 11 as a day of hope and optimism. The feel-good show blossomed with cheerful white looks including a delicate pantsuit, and a billowing kimono dress. And just in case you missed the message of brightness and hope, Nina Simone blaring "Feeling Good," with its chorus of "It's a new dawn" on the soundtrack was there to remind you. The positive vibe caught the attention of the industry heavy hitters decorating the front row, such as Oscar de la Renta, Valentino Garavani, Anna Wintour, Rachel Zoe, Susan Sarandon, and Corinne Bailey Rae.
HOT ITEM: A dandy blood orange jumpsuit.
DESIGNER SOUND: "Feeling Good," Nina Simone
Timo Weiland Spring 2012
VIBE: Happy and exuding confidence, Timo's Spring 2012 line danced on the runway with a freshly sun bathed glow. "It's Basquiat goes to Hawaii," Timo mused to us. Designers Eckstein and Weiland also revealed their collaboration with the Strokes' own Nikolai Fraiture yesterday. The bass player conspired on several looks for the label; one stand out piece included a baseball jacket in a dapper striped chambray.
HOT ITEM: A black and bronze digital print floral dress showed a relaxed surfer chic, encouraging one to daydream about summer nights in Hawaii.
DESIGNER SOUND: Nikolai's exclusive collaborative mixes.
