Rule 1: Pick navy or charcoal
Black suits are for funerals and tuxedos. Navy and charcoal grey are the universally flattering, interview-appropriate choices.
Rule 2: Single-breasted, two-button
It is the safest cut. Works for nearly every body type and every industry.
Rule 3: Fit is everything
An off-the-rack suit altered to fit will always look better than an expensive one that does not. Pay for a tailor.
Rule 4: Conservative tie
Solid or subtle pattern. Avoid novelty.
Rule 5: Polished leather Oxfords
Black or dark brown. Match the belt. Always polished.
