Get the Look: Diane Keaton

The Pants:

Since the wide-leg trouser is one of the biggest changes in silhouettes for the upcoming season, we think there's no better place to start the Keaton look than with a pair of flowing pants. As we mentioned before, J.Crew offers the spot-on Favorite-Fit Solid Keaton Pants for $79.50. When they're named after the actress herself, how could you go wrong? If you want to stay true to Annie Hall, we suggest choosing them in "warm stone," as her character definitely rocked the khakis. Since this is a widespread trend, most stores are doing some interpretation of the wide leg trouser, so you can find a pair at any price point. The Gap weighs in with the Classic Wide Leg Dobby Trousers for just $49.50, while Aéropostale makes the trend downright thrifty (not to mention risk-free) with the Avery Wide Leg Pants for just $19.99. Ultimately, the J.Crew pants are likely to be the most refined, but we wholeheartedly recommend the Aéropostale version if you're pinching pennies. If you'd like to update the look a tad, you can also try the style in denim with these a.n.a. Wide-Leg Jeans for $23.99-$28.99 at JCPenney.

The Shirt, Vest, and Blazer:

The most memorable ensemble from Annie Hall comes when our heroine is first introduced. Keaton's character has just finished a game of tennis and throws on a wonderfully haphazard combination of the above-mentioned pants, a white button down, and a suit vest. It's carefully carefree, and we love it. Fasten up a Classic Button-Front Shirt ($20 at Old Navy) and the Lux Menswear Vest ($48 at Urban Outfitters), and you'll look sleek in seconds. Keaton also wore "oversized" suit blazers in the film, which is to say they weren't the cropped sort that we're so used to seeing these days. Her blazers were more masculine in their proportions since the overall length was longer. This Alvin Valley Navy Stretch Poly 'Park Avenue' Blazer ($199.99 at Bluefly.com) is perfect if you have the money to spend on this staple piece. However, we understand that it might be an investment you're not ready to make, so we also recommend this Manhattan Blazer ($34.80 at Forever 21) because it carries the same shape.

The Accessories:

Last, but certainly not least, are the accessories. Diane Keaton's wispy hair looks tame underneath a black, modified bowler hat; it's not a particularly refined hat, but since so few women sport structured hats at all, the very act of wearing one makes it very chic. We love this Algonquin Cloche Hat for $28 at Urban Outfitters over a low, loose bun. If you don't already know how to knot a tie, it's time to learn as the necktie is crucial. It should be long and wide, so we think any mens tie will do just fine. The BCBG Amrita Geometric Tie ($27 at Macy's) is very similar to the pattern she sports in the movie, but we also think the varied greys in this Alfani Black Split Stripe Tie ($24.99 at Amazon.com) go well with the vest we selected. Keaton also wore a lightweight scarf with her other outfits, much like the scarves that are quite popular these days. We like this Cross Weave Tassel Scarf for $8.80 at Forever 21 because it's a fantastic deal. Try wearing it very loose with one of the afore-mentioned blazers. Slip on a pair of round, mirrored shades like these F7942 Sunglasses ($5.80, also at Forever 21), and you're set.

While you may overlook Diane Keaton today as a star to emulate, you can't deny the influence her most memorable role has made on fashion. Annie Hall is a touchstone for women who want to incorporate a masculine look into their wardrobe, without relinquishing sex appeal. Plus, anyone who inspires a style of pants more than 30 years later deserves our props.
