According to Hollywood mathematics, the size of your bag is inversely proportional to the size of your body.

Nano-sized celebrities like Nicole Ritchie, Lilliputian Lohan and one or both of the Olsen twins have figured out that their sapling-sized bodies can look even smaller next to a Sequoia-sized bag.

Though they may be underfed, it seems what little nourishment does make it to their brains is used wisely: To calculate how many square feet their bag needs to be to, take an 1/8 inch off their waist.

Yes, folks, big bags are shaping up to be the new black pants -- the right ones can be ultra-slimming. And no girl worth her A-list status will be caught drunk at 4am with a demure clutch this fall.

I spied over-the-top, oversized bags at the Celine, Chloe and Chanel Fall 2006 shows, and one or all of them will end up dangling from (or breaking?) the arm of a red carpet runt when the weather turns colder.

Okay, all cheap shots aside, can we B (and C and D) listers benefit from celebrity wisdom? I mean, a big bag can come in handy when you want to lug your laptop or tote your gym clothes to the office. And hey, if it’s slimming to boot, why not add one or two to the wardrobe for those inevitable fat days? Pair it with some super-size sunglasses and you may just vanish!

Since the big Cs of the runway are out of reach for us mortals and mall-shoppers, how can we adopt this trend without having to eat Ramen all winter?

Moderation. Nice but not unnecessarily expensive. Oversized, but not over-the-top. Play Goldilocks for a day and search for one that is “just right.” -- Nichole Robertson

Here a few of my favorites:

Anya by Ananas

The leather is a luscious as the design.

Anna Corinna Sister’s Saddlebag

The unique side seams caught my eye.

Hayden Harnett Ibiza Convertible Tote

This bag folds or expands to accommodate your stash -- brilliant!
