Charismatic Elle magazine creative director Joe Zee launched a new series on the Sundance Channel this week, aimed at helping established but struggling fashion designers.

In "All on the Line," Zee advises and guides designers who are faced with possibly closing their labels. Personalities featured in the eight-episode series include "Project Runway" alum Kara Janx, celebrated '90s designer Gemma Kahng and breakout talent Dana-Maxx Pomerantz.

Check out Zee's exclusive interview with StyleList, above, and a clip from the show below. "All on the Line" airs Tuesdays on the Sundance Channel.

"I haven't been to the States for three months, so all of it's a bit, 'I'm back,'" Kate Winslet said cheerily at the premiere of "Mildred Pierce," her new five-part series which begins on HBO this Sunday.

Winslet plays a character familiar to many from an earlier classic film version -- starring Joan Crawford -- but director Todd Haynes insists his adaptation is more faithful to the novel. (For one thing, added his producing partner Christine Vachon, Crawford insisted on moving the plot to the 1950s so she could wear shoulder-pads.)

But Winslet told StyleList she really enjoyed wearing the '30s costumes of her character.

"I really loved it because it's so different to the '20s and so different to '40s, because we span right across that time period," said the actress, who was wearing a figure-flaunting Stella McCartney dress with a sheer side panel, and shoes by the same designer.

"I loved watching each shape change as the years go by and how the colors shift and change based on the period, but also based on Mildred's success and her own sense of confidence and her own sense of style as well, which really does seem to develop. In the beginning she doesn't have a sense of style."

And would Winslet wear any of the character's pieces herself?

"Under no circumstances," she said firmly.

Part of the problem seems to have been costume designer Ann Roth's strict attention to the underwear and girdles. Evan Rachel Wood -- a StyleList look of the day for her plum Elie Saab premier outfit -- said: "It was uncomfortable. Oh, absolutely. It was tight, it was hot, but you have to do it."

Newly-minted Oscar-winner Melissa Leo added with a slight dash of irony: "Ann Roth was delighted to dress us all in underpants and stockings -- all the stockings you see are garter stockings, me, Kate, everyone wears them."

The actress herself chose a midnight blue Marc Bouwer velvet dress paired with dance-flats, for comfort.

"There's a fashion afoot today," she said, indicating a precipitously high heel near her on the red carpet, "her foot is being broken in those boots, those heels drop to the toe and I cannot do that. I did it as Alice Ward [her celebrated character in "The Fighter"] and those boots almost broke my foot. I had to have sports medicine massage in the middle of shooting."

She continued, "that's the truth about those shoes -- I think they look vile. I think they make women look like they're about to fall over and I think that may be why people like them, but I don't have much to say about them."

And with that, she took herself and her dance shoes into the Ziegfeld Theater for the screening.

Super-mother Stephanie Seymour, 42, showed she still has her model's body on a beach vacation with her husband and children in the exclusive resort of St. Bart's.

Pictures show the relaxed model (who had some redness and tan lines on her back from not enough sunscreen) frolicking in the surf with her family. She even shared a kiss with her billionaire husband -- Peter Brant, 63 -- with whom she was involved in a bitter divorce battle only a year ago.

The family is staying in a luxury mansion on the island which rents for $28,000 a day.

Also enjoying the vacation were children Lily, 6, Harry, 13, and Peter Jr, 17. The eldest child caused something of a stir in January when pictures of he and his mother on the same beach surfaced, showing them looking extra-affectionate.

The teenager, who is becoming a fixture on New York's social circuit in his own right, later responded to the criticism, calling "the beach kiss scandal ... a malicious attack."

Britain's Daily Mail reported the piquant detail that Seymour and her young children happened upon Yves Saint Laurent designer, Stefano Pilati, on the beach, who was sunbathing nude.

"The fashionista wrapped himself up quickly for his encounter with the former model and her children," the paper noted.

Serena Williams has suffered a pulmonary embolism and is seeking treatment at L.A.'s Cedars-Sinai Medical Center, according to her spokeswoman.

The tennis star and Aneres fashion designer was found to have a blood clot in the lungs, which is potentially fatal.

Her rep Nicole Chabot told People magazine: "Monday Serena Williams underwent emergency treatment at Cedars for a hematoma she suffered as a result of treatment for a more critical situation.

"Last week, Serena suffered from a pulmonary embolism which was discovered upon her return to L.A. She had been in New York for doctor appointments for the ongoing issues with her foot. Doctors are continuing to monitor her situation closely to avoid additional complications."

"Tough day...." she Tweeted late Tuesday night, PST.

Williams, 29, was last seen at Elton John's Oscars viewing party in Los Angeles on Sunday night. She is known for her expressive personal style and fashion industry collaborations, including a new line of nail polish.

It's here! Fashion plate Kim Kardashian premiered her first single "Jam (Turn It Up)" this morning on Ryan Seacrest's radio show, and the tune is available on RyanSeacrest.com.

(If you're having trouble with the video above, you can also find it on Too Fab.)

Kourtney Kardashian accompanied her sister to Seacrest's studio for the world premiere.

"We kind of love it, secretively," Seacrest said -- except he was referring to how uncomfortable Kim appeared to be, not her song.

And the lyrics?

"Maybach in the front," Kim sings. "Got any boy that I want ... got my hands up, celebrate like it's my birthday, five more shots of tequila, I'm thirsty."

We think it sounds very... "Jersey Shore." What do you think? If you shop at the Kardashian sisters' Dash store, get used to hearing it on high rotation.

Kim has already shot a video for the track, which has yet to be released.
