Suits and Dresses  
A suit or tailored dress is the most professional attire. Choosing a conservative, classic style is usually a good rule because it is versatile and a good investment. 

Color and Pattern 

Build your professional wardrobe around a neutral color like navy, charcoal gray, black, off-white, camel (beige, khaki, or taupe), or olive. The best patterns for professional suits are solid, houndstooth, tweed, and plaid. 

Shoes 

Shoes should be closed-toe pumps, with heels ranging from one to two inches. Comfort is key. Make sure that your shoes are clean and polished. 

Accessories 

Such accessories as handbags, belts, and scarves should be coordinated with your outfit. Accessories used in moderation add style and personality; too many add confusion. 

Jewelry 
Stay away from dangling earrings, multiple rings, and noisy bracelets. Choose gold, silver, or pearls. Choose button or small hoop earrings in proportion to your size. Pendants or brooches can add sparkle to a blazer lapel or collarless jacket. 

Hair 

Select a hairstyle appropriate for your hair type, face, life-style, profession, and personality. Your hair should be clean, neat, and controlled. Long hair should be pulled away from the face for the most professional look. 

Nails 
Nails should be short and well groomed. Choose a neutral shade or clear nail polish. 

Makeup 

When applying makeup, aim for a natural look.
