Most men who don't like how their suits fit have been paying a tailor for years to fix the wrong thing.
There's one problem in a jacket that no tailor can fix, because it happens before a single stitch is sewn. It's called balance, and it means how the front of the jacket lines up with the back. When a jacket's balance is off, fixing one part usually makes another part worse.
This test has nine short questions, and it takes about four minutes to finish. It will show you what kind of fit problem you have, explain which parts of your jacket aren't working, and tell you which fixes are worth paying for and which ones are not. Grab a jacket and a mirror before you start.
