No matter how nice your tuxedo looks on the hanger, guys should also choose their formalwear for style and comfort. After all, they'll be wearing their attire for anywhere from four to eight emotional and fun--filled hours, so above all else you'll want them to feel comfortable and be able to move easily.
When you're sizing up a tux, your jacket should fit comfortable at the neck and shoulders and fasten easily. Also, try standing and sitting with it buttoned.
The shirt should fit comfortably at the neck, shoulders, and waist. About 1/4 inch to 1/2 inch of your shirt's cuff should show below the jacket sleeve.
Vest buttons should line up with your jacket front, and the vest should button comfortably across your chest. The bottom should slightly overlap the trouser waistband. The waist usually adjusts with a slide strap for a good fit.
Your trousers should button comfortably and feel good when you sit. Many styles have adjustable waistbands, or you can opt for suspenders. The hem should break just over your shoe tops.
If you haven't checked your shoe size in some time have them measured by an expert. Remember that the best time to try on shoes is at the end of the day, because if your feet swell at all, they'll do it then. Better for shoes to be too roomy than too tight.
Always try on a tie before buying or renting one, It should fit snugly around your collar. And remember: No clip-ons!
