nah never half suit
it gives the impression of a person who does a half-fast job, not giving 100%
show ur committed and go the whole 9 yards in a full suit, trust me, it gives u such a better chance
say the employers r trying to decide between u and this guy who has equal abilities and qualifications as u, then they remember hmmm the other guy wore a suit, n the other one only wore half suit.....
i kno it sounds so petty, but seriously they will pick the suit guy.....
