American designers are having their moment in the spotlight at New York Fashion Week, and in the process they’re building a bigger base of fans.

Steven Kolb, executive director of the Council of Fashion Designers of America, said Thursday that he’s heard from buyers at the chicest European stores that they’re increasingly looking to the U.S. for new talent. Derek Lam, for example, is one of the best-selling lines at London’s Harvey Nichols, according to Kolb.

“Today’s designers are talented, and they’re marketers. That’s part of the excitement about American fashion ——– it’s part of the enthusiasm. And the established designers really want to nurture the young designer. That’s very American,” he said.

“American fashion is alive and well,” agreed Style.com’s executive fashion director, Candy Pratts Price, noting that so far this month her Web site has had some 9 million visitors. “New York is looking strong this season. There’s long. There’s short. There’s clothes to grab and go. They reflect the modern way of dressing.”

Fashion Week was set to wrap up Friday with shows by Ralph Lauren and Donna Karan, among other designers.

Vera Wang: poise, grace and elegance. Those are the words for Wang’s spring collection and the designer herself, who went on with her show Thursday despite the death of her father earlier in the day.

She placed a piece of paper on each seat with a simple note that said her presentation was dedicated to the memory of C.C. Wang. When she took her bow at the end of the show, it was clear she had been crying.

Immersing herself in fashion is probably a comfort for Wang. It’s where she practices — and excels at – her craft.

Wang said she was “exploring the emotionally charged space of the geisha’s wardrobe and the ballerina’s rehearsal layers” in her light, delicate collection.

A lame negligee gown with oversized embellished pockets, worn over a nude tulle T-shirt, was like liquid gold, while a whisper-light blush crinkled chiffon dress with an open back was – in a word – stunning.

Outfits that looked like the simple, inviting styles a ballerina might wear after a rehearsal actually had many intricate details woven into them. One of the best examples was a black kimono blouse with a sheer organza back, a navy-wrap tutu skirt with black floral embroidery and sheer black drawstring warm-up pants.

Calvin Klein designer Francisco Costa had a trick up his sleeve to make this season’s loose and breezy dresses just a bit sexier. He put skintight sheaths under voluminous sheer overlays so you could just see enough of the models’ trim figures.

Costa also took spring’s buzzword – “airy” – quite seriously, creating several dresses out of mesh and some of perforated leather.

As always with a Calvin Klein collection, the lines of the clothes were clean, and the colors were cool.

A light sage-green dress with horizontal accordion pleats on the bodice was as wild as it got. Otherwise, the palette was almost entirely white, except for a few outfits in black and yellow. Instead, the focus was on texture, including several looks in a stiff, crocodile-pattern fabric.

Even when they use a restrained hand, Mark Badgley and James Mischka turn out elegant and glamorous gowns.

For spring, they didn’t use as many of the beads, crystals and other embellishments that have become their signature. But the dresses were unmistakably theirs, much to the delight of the jet-setters in the front row, who gave the designers a standing ovation.

An eggshell-colored tulle gown with jewels around a plunging V-neck and waist was soft and sophisticated, and a delicate art deco-style silver tulle vest paired with a long-tiered chiffon skirt could only be described as pretty.

Sharon Stone, their new spokeswoman, would look sleek and sexy in the gold and ivory drop-waist gown with silver trim.

Recently, though, the designers have tried to court younger customers, too. For them, they offered a short ivory organza dress with subtle horizontal rows of beads and a cocktail dress made of black and white chiffon and taffeta cut into vertical zigzag lines.

For all those women – OK, for the handful of superstylish, ultrawealthy women – who were wondering how to incorporate fur into their wardrobes, Gilles Mendel offered several luxurious and lovely answers.

A sand-colored goat jacket – worn with a suede belt, white cotton button-front shirt and cotton-canvas pencil skirt – was the picture of polish, as were a group of white daytime outfits made from broadtail and patent leather.

Another outstanding fur piece was a light-purple goat coat. It was the soft, beautiful color that made it so special.

This collection also featured the rare denim garment, though it was almost unrecognizable in a crisp paneled skirt.

The gowns glided down the runway in front of Kyra Sedgwick, who has worn Mendel on the red carpet. The best was a silvery gray one with vertical swaths of organza. Many of the other gowns featured geometric origami details.
