Recommended Attire
Suit: Conservatively styled (yet currently fashionable) in grey, black, or navy blue. Dress with jacket or coordinated skirt, blouse, and jacket. Blend of natural and synthetic fibers hold shape the best. Make sure it is cleaned and pressed. Hemline should be an appropriate length when seated or standing.
Blouse: White, pastel, or conservative print.
Hose, shoes, and pocketbook: Color-coordinate with your clothes. Make sure to carry an extra pair of hose.
Shoes: Clean and in good repair.
Accessories
Jewelry and scarves: Minimal and simple in style. No jangling bracelets or long, dangling earrings.
Briefcase, attaché case, or folder: Needs to be presentable and in good condition. Instead of both a pocketbook and a briefcase, carry personal items in the briefcase so it is less awkward.
Personal Appearance
Clean and well-groomed.
Hair should be neatly styled.
Cosmetics and perfume should be used with restraint.
Fingernails need to be clean and neatly trimmed. If using nail polish, the color should be conservative and polish should not be chipped.

Dress appropriately for the organization and position you are targeting.
Purchase the best wardrobe you can afford. Don't skimp.
Try on your entire outfit at home several days before your interview. Be sure it is comfortable and fits well.
You only have one chance to make a strong impression! It will all come together with good grooming, a confident self-image, and a positive mental attitude.
