In one sentence, describe what the following article is about:

Style experts build their closets around a few key pieces—all in neutral colors—that can be combined to make the majority of their outfits. Nearly all of them list the same basic pieces:   Tops: white, long-sleeved, button-down dress shirts, neutral-colored crew-neck sweaters, and neutral-colored V-neck T-shirts.  Bottoms: slim-legged black slacks, dark blue skinny jeans, and neutral-colored pencil skirts.  Dresses: little black dress in whatever shape best fits your body type.  Shoes: basic black pumps, black or brown ankle boots, and nude or black ballet flats.  Outerwear: black blazers, beige or black trench coats, and black or neutral-colored motorcycle jackets. Narrow your style down to a set of silhouettes that suit your body. This will help focus your choices and make it easier to buy new clothes and put together outfits.  Once you know what you look best in, stick to that silhouette and buy variations on it. Your silhouette might be tight pants with chunky boots and loose-fitting tops, or high-waisted skirts and dainty heels. When buying clothes, shoes, and accessories keep in mind how you spend your days. This will ensure that you actually wear what you buy. For example, teacher will need a completely different wardrobe (e.g., slacks, pencil skirts, sweaters and flats) than a waitress at a fancy restaurant (e.g., cocktail dresses and heels). Remove everything that doesn’t match your current style tastes. If something doesn’t fit you properly, donate it or have it tailored. Make sure that you feel great in everything that’s in your closet. Be picky. Get rid of anything that you don’t feel good in. It's just taking up space and making it more difficult to compose stylish outfits. Belts, handbags, and statement necklaces are a great way to spice up your classic clothing pieces. Take a little black dress from day to night by switching your flats for heels, and adding a big statement necklace. Earrings and necklaces aren’t the only things you can use to boost your style.  Cinch in your waist and add a retro look to a plain little black dress by combining it with a vintage brown belt and handbag. Wide-brimmed hats have enjoyed popularity for a while now. They’re a great way to dress up most outfits, and are often seen paired with maxi dresses or skinny jeans and blazers. Another must-have accessory for the stylishly minded is sunglasses. Generally big aviators and cat’s eye sunglasses have been popular over the past few years, but you need to choose what looks best on your face. Stand at a sunglasses rack and try on all the different styles. Who knows? Maybe you look best in a pair of small circular sunnies like John Lennon wore.

Summary:
Choose a few classic staples to build your wardrobe around. Have a signature silhouette. Consider your daily routine. Clean out your wardrobe. Spice up your outfits with accessories. Don’t forget about hats, belts, and bags. Invest in a pair of sunglasses.
