Quick Question: I am 5'11, 160 pounds with extremely long arms. A few weeks back I went into Charles Trywhitt in Manhattan and got measured and the lady basically laughed and said they don't make shirts in my proportions (I think my arms were a 36 length and I am a 15 1/2 neck). Is MTM my only option or would buying a bigger size slim fit and getting it tailored work.....one day long ago my long arms were an asset on the bball court now they are haunting me with my dress clothes shopping thanks!
A tailor is your best friend. Get the neck, shoulder and arm length good, and everything is taking in at sides and darting.
MTM is probably your best bet, however, when you consider consistency of sizing and fit available. Not to mention it fits right out of the box.
