In the Black
My time in Basel, Switzerland, at the world's largest watch fair taught me: (1) I can live without fondue, and (2) black watches are huge this fall.

Cash and Carry
When is a wallet not just a wallet? When a chain or strap turns it into an instant shoulder bag. Marc Jacobs's quilted-leather take on this fall trend has a detachable chain. I love it!

Colorblocking 101
Mixing chunks of bold colors is a terrific concept, but last spring too many women were walking around looking like giant Legos. This fall embrace the trend without looking silly by getting the color-block effect from a single item, instead of doing the mix-and-match on your own.

Add a black cashmere sweater to this tricolor skirt, and you're good to go. $275; for stores

This color-blocked shoe gives classic camel a whole new vibe. $30;

Not sure the look is for you? Start small—you'll keep more money in your color-blocked wallet. $85;

The Best and the Brightest
This fall neon is hot, hot, hot. But unless you want to look like a Times Square billboard, use it judiciously—the way you'd use a highlighter pen.
