Your attire is extremely important in showing that you are professional and prepared. It is your most salient feature and thus absolutely critical that you dress according to these guidelines. Remember if you are questioning an outfit, it is better to err on the side of conservative.
MEN
Suits: You should wear a two-piece matching suit. Do not combine a suit jacket with pants that do not match. Long-sleeved shirts are best, even in the summer.
Shoes/Socks: You should wear a leather belt and shoes, with black socks that do not show your skin once seated.
Tie/Jacket: Select a good quality silk tie. Avoid extreme patterns and ties with characters or words.
Colors: Avoid extreme colors. The most appropriate business colors are navy and dark gray. Choose a solid pattern or subtle pin striped suit. The suit should appear solid from a distance.
Facial Hair/Nails: Your appearance should be clean and sharp. If you have facial hair, it should be well groomed and conservative. Avoid designs and unkempt facial hair. Your nails should be cut short and clean.
Jewelry/Cologne: Besides a conservative watch, you should remove all jewelry. If you choose to wear cologne, put very little on so that you do not emit any overly powerful odors; less is best in this area.
WOMEN
Skirt/Pants Suits: Either a skirt or pants suit is fine for an interview. You should wear a matching two-piece suit with a subtle print, soft-colored, blouse. For skirts, we suggest that your skirt cover your thighs when you are seated. Showing any thigh is inappropriate and does not convey a positive message to the employer. A skirt that ends at the knee when you are standing looks professional. Longer skirts are also professional, as long as they are narrow enough, so as not to look billowing. High slits in skirts are not appropriate. A small center slit in a knee-length skirt is appropriate. On a calf length skirt, a slit to the knee to facilitate walking and stair climbing is appropriate. If you are still unsure about your skirt, then err on the side of a nice dress pant. If you are wearing pants, they should be creased and tailored, not tight and flowing, e.g., bell-bottoms.
Shoes/Hosiery: We suggest that you wear close-toed shoes with a conservative heel, e.g., no stilettos, wedges, or platforms. Make sure that you are comfortable and stable in your shoes. Hosiery is appropriate attire. However, we suggest that you do not wear any dense colors, stockings with patterns or designs; instead, wear hosiery that is neutral, sheer, or skin tone.
Purse/Bag: We suggest a small leather purse or briefcase that matches your shoes; however, a pad folio is best.
Colors: Navy, dark gray, brown or black is safe. Avoid the extremes. Choose a solid, subtle weave pattern, or plaid/patter that looks solid from a distance.
Hair/Nails: Your appearance should be clean and sharp. We suggest that your hair and nails be short and clean. Clear, nude, or sheer nail polish is okay.
Jewelry/Make-up/Perfume: We suggest that you wear a conservative watch. Keep your choices simple and leaning towards conservative, e.g. plain pearl necklace/earrings. If you decide to wear make-up, you should keep it conservative and to a minimal. Avoid extreme colors and boisterous scents; less is best.
