Forget changing leaves and harvest moons. For true fashion fiends, fall begins when September's style glossies thud on the doorstep. But flipping through page after page of options can overwhelm even the most enthusiastic shopper. That's why you need our accessories cheat sheet. It's a quick guide to what's out, what's in and how to work the runway's best belts, shoes and bags into your real-life wardrobe.

The low-slung belt, sported here by Sandra Bullock, has long been a style staple (paired with low-rise jeans, natch). But it doesn't do any favors for those with curvier figures. Didn't Sandy learn anything from her "Miss Congeniality" makeover session?

Dolce & Gabbana's stunning metal waist cincher ($1,235- $6,195; call 212-249- 4100 for details) rocked the runway, paired with looks from structured dresses to fur coats. Its mirrored exterior won't exactly whittle your middle, but we're guessing D&G's size 0 clientele doesn't mind.

Unless you're channeling Gisele (or Joan of Arc), opt for WCM's understated take on the corset belt ($120 at Nordstrom stores and www.nordstrom.com). It features trendy buckle detailing and is extra wide, but glossy black patent tones down the look.

A few years back, pointy-toed stilettos were the last word in sex appeal. But as all those "Sex and the City" acolytes discovered, squashed tootsies tend to be more ouch-inducing than alluring.

Fendi's turquoise platform sandals ($615 at Neiman Marcus stores and www.neiman
marcus.com) would add a jolt of quirk to any autumn ensemble, and their so-1980s hue is on-trend for fall.

This multicolored suede sandal from Nine West ($89 at Nine West stores and www.ninewest.com) is an easy-to-wear alternative. Its heel is chunkier, which means you'll do less tottering, and the more subdued palette is less likely to invoke buyer's remorse.

The daytime clutch (seen here by J. Crew) is still a viable option for those women who are so put together that all they need is a lipstick, a cellphone and keys. Now, as for the other 90 percent of us ....

Actress Rachel Bilson was one of the first celebs to tote Zac Posen's Aurora frame bag ($1,500 at www.net-a-porter.com). The structured shape and vibrant color add up to the ultimate in arm candy.

ISO an eye-popping satchel at a palatable price? Rampage's crocodile doctor bag ($78 at www.rampage.com in late September) is a smart alternative, thanks to its glossy finish, matte hardware and simple shape.
The ombre trend is suited for this season of transitions.
