Five key items to buy now

(InStyle) -- InStyle experts sorted through the season's strongest and most-wearable looks and selected five fashionable must-haves for fall.

1. School-boy blazer

Choose a sport coat that is tailored specifically for women. No boys allowed in one of these jackets: The flattering look is for well-defined waists only.

This take on haberdashery has little to do with button-downs, boyfriend sweaters or wearing his ties. In fact, if your BF has these clothes in his closet, you two need to have a chat. Peek at what you need to buy »

Sporting highly nipped waists, slouchy trousers, private-school sport coats, embroidered waistcoats and wide-peaked lapels, the mood is Edwardian and rather foppish.

This style bear all the sartorial signposts of classic men's tailoring but allow working women a way through the Looking Glass ceiling without looking like they're in a unisex uniform.

2. Slouchy pleated trousers

Time to ditch the skinny pants for a pair of slouchy pleated trousers with a higher waist band and a wider flare. They work best paired with a soft full top and chunky heels.

In case you'd forgotten (thanks to skinny jeans): It's really nice to have some place to put your hands, especially if it makes you feel like Katharine Hepburn.

With a higher waistband, a wider flare or even a cropped hem, these trousers come off best paired with a soft full top and chunky heels.

3. Colorful bag

Make a statement with a bold bag. This accessory will add a splash of color to fall's gray and silver trends.

4. Chunky knit cardigan

When it comes to dressing for fall, there's nothing quite like being warm and cozy -- and chic if you're wearing this Coach cardigan --in a chunky knit sweater.

Whether choosing a sweater coat, cardigan, tunic or oversize turtleneck, the idea is to imagine yourself in a warm and fuzzy hug.

The drawback to sinking into deep, textured handknits is overheated interiors. You may want to treat knits as outerwear with a thin layer underneath.

5. Stacked heel oxfords

Add a dash of masculine style with this fall standout. The stacked heel adds just the right amount of feminine flair.

Pair them with knee-length dresses and stovepipe pants. They're a chic alternative to loafers for work; patterned socks and hosiery match well.

Look for perforated, kiltie details and signature laces, or ones with ribbon flourishes. Masculine in shape but feminine in design, they look great with skirts. E-mail to a friend
