The latest gala isn’t the first time the gang has stepped in as fashion icons. A 1984 book called “Snoopy in Fashion” features beagle plush toys photographed in mini apparel from Gucci, Fendi, Armani and nearly 100 others. The pieces are still displayed in museums. In 2005, a Barcelona designer did a Peanuts-inspired collection, which was followed by a China fashion show last year. “We had to bring something like this to the States,” says Melissa Menta, vice president at United Media, which licenses Peanuts.

The latest event is sponsored by MetLife (also behind those Snoopy commercials), and the dresses will be sold on eBay for the charity Dress for Success. Isaac Mizrahi is doing a Charlie Brown frock. Other contributors: Betsey Johnson, Pamella Roland, Kristin Chenoweth (“You’re a Good Man, Charlie Brown”) and Laura Bennett of “Project Runway.” “I made a fabulous cocktail dress with feathers, which is a penchant of mine,” she says of her yellow Woodstock garment. She hopes it will go for about $7,000. Good grief, Charlie Brown!
