Split into three themes -- Neo Pure, Neo Patch, and Neo Precious -- Moss's collection was inspired by the '70s, as well as Longchamp's archives.
"I had a couple of vintage bags from the Seventies that I picked up in secondhand shops in Florence and Marrakech," Moss explains in a statement.
"One of them had a patchwork design. I showed it to Sophie [Delafontaine, Longchamp's artistic director], and she said, 'Come and have a look through our archives.' And that was how I found out that, at exactly the same time, Longchamp had been working with patchwork and lambskin."
Moss says the two diagonal-striped patchwork bags, which make up the Neo Patch mini collection, are her favorite designs for Fall 2010.
To create the textured color-block look, the supermodel/designer used embossed calfskin and her favorite hues of pale gray, jade green, and bright red, along with black and white.
"The leather is so soft, it's like the softest skin you can imagine," Moss enthuses. "I love the modern feel of the handles and the different textures."
The semi-slouchy bags have chic, antiqued-metal chain handles, crocodile-style calfskin trim, and zebra-print lining.
The third mini collection, Neo Precious, goes bold with sleek, brightly colored clutches in crocodile-embossed leather embellished with chunky crystals.
"I have always loved exotic leathers," Moss says of the bags. "It's the richness of them that attracts me. It's the same with the ornaments on the clutches -- I just love the idea of having jewels on a bag."
In addition to these new Fall 2010 designs, Moss is also bringing back the popular Rock'N Casual theme of her debut collection for a second season, making over the Ladbroke hobo, the Glastonbury messenger, and the Gloucester duffel in three new colors: charcoal gray, rich burgundy, and racing green.
"It wasn't my intention to be English," Moss says of the British-schoolgirl-uniform hues, "but these are the sort of classic colors I am always drawn to. I guess I'm just that kind of girl!"
We, and a million other women, are that girl, too.
