An invitation to a potluck meal calls to mind Pyrex dishes filled with green bean casserole and Tupperware loaded down with hand-frosted cupcakes. But on the Upper East Side, things are done a little differently.

The new cookbook "Park Avenue Potluck Celebrations," which benefits The Society of Memorial Sloan Kettering Cancer Center, features tried-and-true recipes from some of society's top hostesses, including Coco Kopelman and Eugenie Niven. In the spirit of sharing, here are a few dishes handed down from their kitchens to yours. Viking stove not required.

I recently spent an afternoon with Marcus Samuelsson and Zac Posen in Samuelsson's Harlem apartment. The two were cooking a late lunch together as a sort of dry run for the dinner they'll be making with Giada De Laurentiis on Saturday as part of the New York City Food & Wine Festival. (Ticket sales from the event will benefit hunger relief organizations Food Bank For New York City and Share Our Strength.)

We got to talking about the similarities between the food and fashion worlds -- how everything is rooted in the visual, why it's important to start with good ingredients and good fabrics and how both disciplines unify form and function.

Though he's been dating designer L'Wren Scott for just a few years, Mick Jagger is certainly no newbie to the fashion world. As a Rolling Stone, he worked with "loads of stylists, millions of them," he told me at the dinner he threw during New York Fashion Week for his girlfriend. But lately he's become particularly interested in the production side of things. Here's a snippet of our conversation about style -- men's, women's and his great-grandfather's.

For the last few days, talk among the fashion crowd sounds a little like "green is the new black," "short is the new long," "faux is the new fur." The same goes for foodies this week: restaurant SD26 is so the new San Domenico.

Since opening in 1988, San Domenico has operated as a posh Italian restaurant on Central Park South, favored by Uptown society and power players. But when the rent was quadrupled this fall, owners and father-daughter team Tony and Marisa May were forced to move the eatery to a more affordable spot on 26th Street (Marea took over the Central Park space).

The Eye desk sees some interesting books pass our desks, but the one that arrived on Wednesday took the cake. "How to be Famous: Our Guide to Looking the Part, Playing the Press and Becoming a Tabloid Fixture," by Heidi Montag and Spencer Pratt. If only we were kidding.

The book's cover is designed to look like a tabloid, lots of pinks and yellows and a happy couple shot of Speidi. Inside, there are the same paparazzi shots of the two reality stars that have run ad nauseum in Us Weekly, Star, InTouch and the like. But it seems this time the photos serve another purpose: to illustrate Pratt and Montag's erudite prose about how to achieve and maintain celebrity status.

With all the talk of Malia and Sasha Obama, it's easy to forget that less than a year ago there was another pair of Presidential daughters in the spotlight. But on Thursday, Barbara Bush and Jenna Bush Hager did their best to draw attention to UNICEF and its Project Sprinkles effort, which helps fight malnutrition among children in Guatemala. While her peers mingled
around the bar at The Gates, a newly brunette (and, it appears, newly poised) Jenna Bush spoke with WWD about why this charity is close to her heart and how she and sister Barbara don't see as much of their parents these days as they'd like.

WWD: How did you decide to support UNICEF?
Jenna Bush: I worked in the field with UNICEF in Latin America for a year. I wanted to find a way to still keep engaged even though I don't still live in the developing world, and there weren't many ways for my generation to be involved. [Now] we have 30 really dynamic people on UNICEF's Next Generation, this new committee, who are really interested in making visible
change. So it's fun to be with such an energetic group that has so many
different ideas on how to improve the world.
 
WWD:: Why Guatemala?
J.B.: Guatemala has the worst malnutrition rates in Latin America, and one of the worst in the world. It seems like such an easy problem to fix, but it's really not. [Project] Sprinkles is fantastic because it's so cheap and effective. A kid can put [the sprinkles, which is a packet of powdered vitamins] on something, an unfortified tortilla, and it provides them with all the nutrients they need for a day.
 

Long before Valentino was luring crowds to theaters with his documentary "The Last Emperor," Isaac Mizrahi hit the big screen in "Unzipped." The 1995 flick, directed by Mizrahi's then-boyfriend Douglas Keeve, follows the designer through the making of his fall 1994 collection (you may remember it as the one with all the neon faux fur).

Fran Lebowitz and Diane von Furstenberg are long-time friends, so it was little surprise seeing the acerbic writer at von Furstenberg's store last Wednesday night for a party. The bash was for Gloria Vanderbilt and her new book "Obsession: An Erotic Tale" (which von Furstenberg confirmed was "very, very, very, very erotic).

When someone bellies up to a bar by themselves, they're usually looking for the bartender to pour them a drink and lend them an ear -- not bust out a camera and pop a flashbulb.

Photographer Sarah Stolfa, who worked for almost a decade at Philadelphia dive McGlinchey's, didn't use quite such guerilla tactics when shooting her loyal customers for her book "The Regulars," but she does shed light on what are otherwise private moments.

"I was very interested in photographing people in this public space where it's okay to go alone but also wanting interaction with other people," she says. "I would take my time [between shots] to try and see if I could get that public mask that people have to kind of dissolve."

Over the last few weeks, my colleague Jessica Iredale and I have been mourning Michael Jackson. Yes, we recognize that he was accused of child molestation and his behavior over the last few years has made him the mayor of Crazy Town (or Neverland, as the case may be). But the man we choose to remember is the musician. Which is why our ensembles as of late have been more Motown than 7th Avenue.

The day after his death, I wore silver hi-top Hogan sneakers to the office. Not a literal imitation of Jackson, but I felt they were shoes meant to moonwalk. Then on Tuesday, the day of Jackson's memorial, Jessica came into the office in a metallic silver Yigal Azrouel cardigan. "It's my tribute outfit," she said.

Aside from one mail room staffer in a Michael Jackson concert t-shirt, there were very few editors watching the televised memorial coverage with us (could it be that everyone, finally, is over this?), leaving Jessica and me to think we were all alone in our pop culture grief. That is until I got a press release about Kate Moss, spotted in London, wearing Repetto's black patent leather "Jackson" loafer.

"She's one of us," Jessica said enthusiastically after I showed her the email.

Not really, considering that neither of us are eternally chic, formerly drug-addled supermodels. But it appears that when it comes to Michael Jackson, we're not the only fashion folk paying tribute. And if we hit Bergdorf's fast enough, we can at least walk in her shoes.
