• A suit’s gotta fit right or it isn’t worth wearing.
• In order to make sure that it does fit right, find yourself a good tailor.
• You’ll never go wrong wearing at two-button suit with a fairly narrow lapel. It’s both classic and completely modern.
• Flat-front, relatively trim pants; very little break at the ankle.
• You should be able to easily cup your hands beneath the hem of the jacket; if you can’t, it’s too long.
• Show some cuff. It’s the mark of a (well-dressed) gentleman.
• Dress with the season—cotton suits in summer; tweeds, flannels, and corduroys in winter.
• If you’re going to wear a patterned suit, keep the patterns subtle. You want a smart suit, not a kooky one.
• If you ever can afford to get a bespoke suit, get one made. It’s worth every penny.
