DIOR CRUISIN': Dior made its annual Cruise stop in Los Angeles this week with back-to-back in-store events in its Rodeo Drive boutique. On Tuesday, along with C magazine, the company hosted a lunch for Step Up Women's Network for which the unofficial dress code was white. "I didn't get the memo," one of the many black-clad guests remarked. But singletons Jamie Tisch and Shiva Rose McDermott did, most likely tipped off by white-clad Katherine Ross. The next night was a fete for Dior's 60th Anniversary tome, hosted by the Los Angeles County Museum of Art Costume Council. Instead of the usual fashion plates, photo-shy philanthropists like Rosalind and Hal Millstone mingled with models.

SCENT OF EVE: R&B star Eve was on hand at Thursday's celebration for the MAC AIDS Foundation, which has raised $100 million to help fight HIV and AIDS around the world. Eve made a guest appearance at MAC's Upper West Side store with fellow Viva Glam spokeswoman Dita Von Teese and said her own scent is in the works. "I can't wait to do a fragrance. I'm sure it will happen soon," said Eve. "I not only want to meet the nose, but I want to be the nose. I want to be that person who's in there putting stuff in the little bottles. I'm obsessed with smells." Although she doesn't know quite yet the overall theme of her first fragrance, she already has an idea what it will smell like: "I'm a floral person. I like something not too heavy, but something that lasts." Von Teese isn't working on a fragrance but has a new beauty book planned for release late next year. "I wanted a rule-breaking beauty book that's about retro glamour and eccentric makeup — a book that teaches you how to put it on," said Von Teese.

HEY BIG SPENDERS: Five individuals with bucks to burn peeled off a total of $2.7 million in three minutes flat to buy five of the first-ever Mercedes-Benz SLR McLaren Roadster convertibles. Their route? A holiday promotion staged at 2 p.m. on Wednesday by Saks Fifth Avenue, which offered the luxury cars for $542,000 apiece and donated $10,000 of the proceeds from each of the five vehicles purchased to St. Jude Children's Research Hospital in Memphis. In addition to the limited edition Mercedes, the half-million or so dished out by the gift buyers will bring them a trip to Monaco for the 2008 Formula One race, a helicopter ride from Monaco to Provence, France, for private lessons from the professionals at the Circuit Paul Ricard racetrack, plus accommodations and travel.
