Shopping Rules:
• A formal button-front shirt should be stark white or cream. And ruffles are a definite no.
• If his pants are properly tailored, there's no need for suspenders or a cummerbund.
• A bow tie is essential—he should learn to tie one for his wedding, not wear a clip-on.
• Single-breasted, single-button jackets are timeless for a reason—they'll trim his waist and broaden his shoulders.
