7 Cheers For Sweater Weather!

Start off the workweek with a classic, sharp look that skips busy prints and bold colors. Reese Witherspoon's basic white sweater looked especially clean worn with a black skirt and accessories.

If a late night at the office has you desperately wishing you could just wear a sweatshirt into the office, then go for the next best thing: a warm crewneck sweater. While the piece is definitely weekend friendly, it can easily be dressed up for your 9-to-5 with the right shoes. In Jaime King's case, that meant a pair of embellished black flats.

Rose-covered or not, any sweater can be dressed up with a styling trick like the one Jessica Alba employed. Layer it over a button-down done all the way to the top, making sure that the collar is pulled out and over the neckline of your knit. Add a statement necklace for a final bit of pizzazz, and you're ready for a dinner out with clients.

While Ashley Greene's easy look would've worked with a thin, solid-colored top, upon closer look, this one has something extra. The sleeves and hem were edged with a spot of tie-dye, turning the would-be preppy look into something with a dash of hippie.

Make your casual Friday playful with an animal-print sweater. The style's had a big moment this year, and they're a dime a dozen, making it easy to find whatever creature speaks to you. Hilary Duff's easy outfit made it known that she's an elephant girl.

An oversize, asymmetrical hemline like Lea Michele's might look sloppy in the workplace, but the weekend is a different story. There's something inherently relaxed about the shapeless piece, which is perfect for pairing with leggings or skinny jeans. And while it's ideal for lounging around at home, there's a sexiness to the way it slips off the shoulder that lets it work for drinks out, too.

In its old-school, Fair Isle iteration, the sweater seems made for running errands à la Elle Macpherson. She bundled up in Aspen, wearing hers over a plaid shirt with leggings and a furry trapper hat. Extra points if you match your sunglasses!
