ive seen lots of men dress up that way, where they wear a suit but don't have on a tie, and I've done that myself also.

Depends on the suit, some are tailored to look alright without a tie.
But as a general rule, I'll always wear the tie. It's a fashion thing. A good silk tie which matches the suit well, is just as important to the overall look as a good pair of cufflinks.0
