Specifics for Men’s Casual
Ties: Ties are generally not necessary for business casual, but if you are in doubt, you can wear a tie.
Shirts: Long-sleeved shirts are considered dressier than short-sleeved and are appropriate even in summer. Choosing white or light blue solid, or conservative stripes is your safest bet. Polo shirts (tucked in, of course) are acceptable in more casual situations.
Socks: Do wear dark socks, mid-calf length so no skin is visible when you sit down.
Shoes: Shoes that are in good condition should be worn. No sandals, athletic shoes or hiking boots.
Hair and Facial Hair: Neatly groomed hair. If you happen to have long hair, consider putting it in a ponytail to keep it out of your face. Beards and mustaches should be well-groomed.
Jewelry: Wear a conservative watch. If you choose to wear other jewelry, be conservative. For conservative industries, don’t wear earrings.
