You may not be an expert tailor, but you don't need any special skills to know if a suit fits perfectly. You can measure each part of the jacket and pants by eyeballing where they fall, and by using a few tricks with your hands.
Esquire lines out seven things you can check right off the bat:
- Shoulder pads end with your shoulders.
- Your flat hand should slip easily into your suit under the lapels when the top (or middle) button is fastened. If you put a fist in, the suit should pull at the button.
- The top button of a two-button suit -- or the middle button of a three-button suit -- should not fall below your navel.
- With your arms at your sides, your knuckles should be even with the bottom of your jacket.
- Jacket sleeves should fall where the base of your thumb meets your wrist.
- Between a quarter and a half inch of shirt cuff should be visible.
- One inch of break [in the leg].
If any of these don't fit the way they're supposed to, then you'll need to head to a tailor. But you can at least see what needs tailoring just by following these simple tips. Hit the link to learn more.
