Guy’s clothing can go from casual to formal with just a few accessories. Today, many business men are no longer required to wear a suit and tie to work, because business casual clothing is so popular. One of the best casual outfits to wear is a long-sleeve dress shirt with a pair of trousers.

Khaki trousers and light-weight wool slacks are particularly trendy for guys, and have become part of the “office uniform” for many men.

On the occasion when a guy is going straight from work to a high-class restaurant or other events where casual clothing isn’t appropriate, he can quickly alter his outfit to a more formal look that’s perfect for fine dining or even a hot date.

Just add a blazer on top of the dress shirt — and perhaps a tie or pocket square — and a man can go from the office to the opera without worrying.

Business casual clothing is often flexible and sometimes sneakers or other sport shoes are allowed in the office. It’s important for guys who do wear sport shoes in work to keep a pair of dress shoes in the car for a quick shoe change. A nice pair of loafers will usually be a perfect choice.
