I am 6 feet tall. I bought a solid navy and a solid grey from Brooks Brothers yesterday (got about 30% each of $900). Both suits are a 42L. I get the long because I have very long arms and usually only the 42L sleeves have enough material to full cover my arm. I am trying to figure out if the jacket is actually too long. If this is the case, then I may have to get some bespoke suits which is outside of my budget right now. The salesperson at BB said that from the top of the collar to the bottom of the jacket should be the same distance as the bottom of the jacket to the ground. My measurements: Collar to bottom of jacket: 32 inches Bottom of jacket to grough: 30.5 inches Is this the proper jacket length?
