Summer may still be sweltering, but fashionistas know it’s past time to purchase swimwear and sandals. New fall fashions are flooding into Washington stores, and we’ve got the scoop on what trends are making a splash.

Bloomingdale’s ready-to-wear fashion director Stephanie Solomon credits Hollywood for inspiring many of this fall’s must-have trends, including one of the most popular looks—the ’80s revival. “Movies offer a compelling fantasy world where anything is possible,” says Solomon. “Film has a way of captivating and inspiring its audience. [Designers such as] Michael Kors and Ralph Lauren looked to the trends and cultural influences of the 1980s and reinterpreted its finest moments to create a modern look for fall.”

Many designers were also inspired by a more conservative era, creating Mad Men-esque fashions evocative of the ’40s, ’50s and ’60s. Tailored jackets, plaid, and classic dresses in jewel-tone colors ruled the fall runways and fit right in for Washington offices.

Lest you fear you’ll need to shell out major moolah to look on-trend, designers have incorporated many top looks from fall 2008 and spring 2009 into this year’s. See our “old and new” chart (below) for slight changes, but rest assured you can keep your booties, metallics, slim-cut pants and statement necklaces in the front of your closet for at least a few more months.

Additionally, this season’s big pieces are incorporating twists on classics. It’s the perfect time to stock up on basics such as cashmere sweaters, blazers, sheath dresses, and overcoats that can be worn for seasons to come.

Here are a few of our favorite looks for fall 2009: 

Ladylike and Lovely
Whether you live for color or love your little black dress, you’ll find a frock that suits your style this season. Form-fitting dresses and feminine accents ruled the runways. Unlike previous seasons, this year’s look is more about mature beauty than girly-girl chic—hemlines often hit at the knee or below, and the look is streamlined.
