To save money, new workers might consider creating a capsule wardrobe. That's a closet with just two or three dozen quality, versatile basics.
Instead of an overflowing closest, say, with polka-dot crop tops, green miniskirts, and four-year-old shirts with stubborn armpit stains, you pare your wardrobe down to a few things that can be mixed and matched.
For women, Savasuk recommended three to five basic bottoms with five to 10 blouses and shirts — or five to 10 dresses. De Bease recommended two to three pants, eight tops, and two casual jackets or cardigans.
"With the addition of necklaces, earrings, shoes and scarves that suit your character and personality, and you can personalize these professional outfits to reflect your own personal style," Savasuk told Business Insider.
For men, Savasuk said to purchase three to five pairs of pants with five to 10 high-quality button-downs.
"If ties are required, purchase a few that reflect your character and personality, so you can bring your own flavor to 'business professional,'" Savasuk said.
And stick to a few colors. Griffin recommended picking a neutral base like black or gray for most of your pieces, and a few articles of clothing in accent colors like blue or red.
"Everything should work together," Griffin told Business Insider. "You shouldn't have any closet singletons."
