How to Try On a Suit or Tuxedo

To check the fit, you need to know where to look. Use this guide to make sure the sizes and details are right.

LET’S TRY IT ON.

Whether you have experience suiting up or not, we have a few tips for using the extra time with your items to check the most important part of the suit—the fit.

Ready to check it? Let’s get started.

Start with a dress shirt and dress shoes.

To get an accurate idea of how everything fits, make sure to wear your dress shirt with your suit or tux, and dress shoes to check the length of your pants.

Check the shirt.

SHIRT NECK

Button your shirt all the way to the top. One or two fingers should fit comfortably between your neck and the shirt collar.

SHIRT BODY

You should have room to move without a lot of extra waistline fabric billowing out of your pants, but if the shirt fabric pulls around the buttons, your shirt is too tight.

Too big, perfect, too tight.

SHIRT SLEEVES

Your shirt sleeves should end right at your wrists—just covering the nubby wrist bone above each hand. Be sure to keep your arms down at your sides when you check the sleeve length.

Too long, perfect, too short.

Try on the pants.

PANT WAIST

Suit pants are designed to sit up a little higher on the waist, with less stretch in the waist than casual pants or denim, but they shouldn’t be uncomfortably tight.

If the waist is a little loose, you can wear a belt (with suit pants) or adjust the waist (on tuxedo pants). Suspenders also work with both suit and tuxedo pants.

PANT LENGTH (INSEAM)

For a modern look, the pant fabric should only touch the tops of your shoes without creating much of a fold. If you have multiple folds of fabric, your pants are too long.

Try on the jacket.

Suits and tuxedos are designed to have just one button fastened. If your suit has two buttons, only fasten the top button.

JACKET CHEST

The lapels of your jacket should lie flat against your chest. If they billow out when the jacket button is fastened, your jacket is too tight. If you can’t see any contour in your chest or waist, it’s probably a little big.

Too big, perfect, too tight.

Next check the jacket shoulders—they should end naturally at the point where your shoulder becomes your arm. If the jacket shoulders hang out far past your actual shoulders, your jacket chest size is too big.

JACKET LENGTH

Suit and tuxedo jackets come in different lengths. The body of the jacket should end around the middle of your seat. If the jacket hangs down past your seat it’s probably too long. If it ends up above your seat, it’s too short.

Too long, perfect, too short.

JACKET SLEEVES

Be sure to keep your arms relaxed at your sides. The jacket sleeves should end at your nubby wrist bone. If your jacket sleeves are the right length, you should see ¼” to ½” of shirt cuff peeking out underneath.

Get a second opinion.

The mirror is great, but getting another perspective can help, too. Ask your partner or a friend to help you check the details when you try on your suit.
