Chic fall hats from Livity, Stewart+Brown, and the Hempest

Why It's Good:

Hats have once again bobbed to the surface of style: Right now, le chapeau is très, très chic. The right hat can instantly change any outfit from drab to fab, so top off your look (or just hide bed-head) with one of these four key shapes.

Why It's Green:

We love any trend with style longevity (less chance of ending up in landfills), and if it's sustainable, even better. Three of the hats (see below) are made from a blend of cotton and hemp, the latter of which is a rapidly renewable, versatile plant requiring less water and pesticides/fertilizers (if any) to grow. Stewart+Brown gathers and produces its cashmere from herders in Mongolia, supporting economic sustainability; and is a member of 1% For the Planet, with portions of sales going to environmental causes.

Mad About Hats

You may fear hat-head, or feel you're just not a "hat person." We urge you to give this oft-overlooked wardrobe essential another try. Here, four hat trends that lend effortless panache to your favorite fall looks:

  The Cloche

(main picture): Wildly popular with flappers in the 20s, this head-hugging style crowned fall runways; charming with slim dresses, high-collar coats, tailored suits, and belted trousers. We love: Stewart+Brown's Peasant Cap, a slightly boho take in Mongolian cashmere, $165.

  The Fedora

(second from top, on left): Noir-slick and sexy as ever, this classic tipped-brim gender-bender is coveted from the runway to the silver screen. Smashing with wide-leg trousers, pinstripes, pencil skirts, patent ankle boots and your favorite jeans. We love: Livity Outernational's Don Mon Fedora in hemp/cotton twill, $36.

  The Newsboy

(top picture, on left): Worn at the hint of an angle, this jaunty blouson cap with snappy brim is the versatile casual fave of the season. Wear with button-downs or vests, jeans, cropped trenches and flats. We love: Livity Outernational’s hemp/corduroy Disinformation Newsboy, in this season's most alluring color, cobalt, $30.

  The Military Cap

(bottom picture, on left): This cap can alter its personality according to your mood: downtown punk (hoops, dark or worn denim); mod (mini-dresses and tights); or equestrian-chic (cropped pants, tall boots, leather gloves). We love: The Hempest's Militant Cap, $36. Aren't hats just tops?—Elizabeth McMullen
