When Job-Hunting: Dress for Success, by Dr. Randall Hansen.
The standard job interviewing attire for men is a conservative dark navy or gray
two-piece business suit (of natural fibers, such as wool, if possible),
a white long-sleeved button-down dress shirt, a conservative silk tie (that matches the
colors in your suit),
and nicely polished dress shoes.
If you do not own a suit, or the company is
a bit more informal, then you should wear a conservative sports coat (no plaids
or wild patterns and preferably a dark color), nicely pressed dress slacks, a
white long-sleeved button-down shirt, a conservative silk tie, and nicely
polished dress shoes.
Your belt should always match your shoes.
If you have a beard or mustache, your facial hair should be neatly trimmed.
If you have any visible body parts pierced, most experts recommend removing all
jewelry, including earrings. Do not have excessive body odor or cologne.
So, what are some sample outfits?
