Neck ties are over. They used to be central to mens' fashion. Now if you wear one it's because you have to, which denotes low status. Like, the worst is chinos, a cheap shirt and tie, with a windbreaker instead of a blazer. Also: black sneakers. For some crazy reason, it's actually higher status to wear designer sweats around.

The look for business is slacks, a good pressed shirt, a fitted blazer with no shoulder pads, and NO TIE. Top neck button undone. It's also more comfortable. Even top execs are dressing like this. Ties are only necessary in the most formal occasions.
