1. KNOW YOUR SIZE AND MEASUREMENTS
Having your exact measurements on hand goes a long way toward attaining a polished look — especially when you’re shopping online. You can try to measure yourself, but chances are you’ll completely screw that up. So instead, find a store that’ll measure you for free; Men’s Wearhouse is one, but there are many others. (Even though the service is free, it never hurts to tip the guy measuring you.) At the bare minimum, you’ll want to know your inseam, hip, chest, neck, and sleeve lengths. Memorize this information, or, even better, store it in your phone so you always have it on hand. Oh, and be honest with yourself about any weight you may have gained since you were measured last; wearing pants with a too-small waist ends up making you look fatter, not slimmer.
