No matter how nice your wedding tuxedo looks on that hanger, it won't mean a thing if it ain't got You definitely don't want a high-water, too-tight or too-loose suit that will make you look like a little boy playing dress up on your wedding day. Make sure you get the right size by following these guidelines.

The Basics

Here's what to look for when you're sizing up a tux:

  • Tuxedo jacket: Your formalwear jacket should fit comfortably at the neck and shoulders and fasten easily. Don’t forget to move around in it buttoned while standing (you should unbutton while sitting)..
  • Tuxedo shirt: About a quarter-inch of your shirt's cuff should show below the jacket sleeve. It should fit comfortably at the neck, shoulders and waist.
  • Vest: Vest buttons should line up with your jacket front, and the vest should button comfortably across your chest with the bottom button left undone. The bottom should slightly overlap the trouser waistband. The vest's waist can usually be adjusted with a slide strap in the back. Consider a vest with a full back. When jackets come off during the reception, guests will see the real deal instead of a strap and the back of your shirt.
  • Trousers: These should button comfortably and feel good when you sit. The hem should break just over the tops of your shoes.
  • Bow tie: Always try on a bow tie before buying or renting one. It should fit snugly around your collar. (And if you’re going with a self-tie, learn how to tie it!)
  • Shoes: Remember that the best time to try on shoes is at the end of the day, when your feet are slightly swollen (which they'll almost certainly be by the end of the wedding). Better for shoes to be too roomy than too tight. It’s also a good idea to wear them around the house to help break them in for the wedding day.

Comfort Is Key

You should be able to move easily -- do lots of twists, turns and arm raises when you try on tuxedos for your wedding. After all, you'll be wearing those duds for four to eight emotional, fun-filled hours.

Size It Up

It's a good idea for everyone to try on their formalwear at least two days before the wedding. Sounds like a no-brainer, right? You'd be surprised. Many mismatched bridal parties or ill-fitting suit jackets result from neglecting this simple step. In most cases, you’ll try it on at the store or tailor, so you’ll avoid having to run back to the shop if it needs further tweaking.
