To create a corporate ensemble, wear your black pinstripe pants as a suit with a matching jacket or paired with a jacket in black, gray or navy blue. A versatile tweed jacket also complements pinstripe pants. If you work in a more laid-back environment, wear a jacket in a color such as red, green or pink and push up the sleeves. Apple shapes should avoid double-breasted jackets; these create the illusion of excess weight in the stomach area. If you are pear-shaped, choose jackets that rest on your hips or thighs. Cropped jackets fit well on hourglass and wedge shapes -- these jackets will draw attention to a slim waist.

You'll look impeccably tailored and professional in a white, navy, gray or beige collared shirt combined with your pinstripe pants. A fitted shirt with vertical darts below the bust accentuates the chest and adds a tailored look to the pants, so this shirt is flattering for anyone with a small bust. Horizontal darts on the sides of the bust highlight curves and work well for an hourglass figure. A simple T-shirt or polo shirt in any color may be suitable for a relaxed office setting. Tuck the shirts in, and wear a belt. Tops with open necklines are suitable for all body types, accentuating the neck and collarbone to give the appearance of a taller stature.

In cooler weather, wear your black pinstripe pants with just about any style of sweater. Bright colored sweaters will liven up your look. Cardigans can be worn buttoned down for a conservative look or open for a relaxed touch. Turtlenecks are suitable if you have a long neck. Apple shapes look best in V-neck sweaters, which create the illusion of a longer torso. Square and boat necks are flattering on pear shapes. To continue the classic style, accessorize these sweaters with jewelry such as pearls, chain necklaces or chokers.

When you're going out on the town or to a party, combine these menswear-inspired pants with tops that provide a feminine touch. Perk up your black pinstripe pants with a ruffled or lace top for an after-work gathering. For a cocktail party, wear a top with embellishments on the neckline or throughout. Tops with sequins, beads or faux gemstones dress up the pants for a holiday or cocktail party. Accessorize with classic pumps, slings or peep-toe heels. A beaded, satin or leather clutch in a pop of color adds a statement to the ensemble.
