Instead of wasting money on a "name" suit that doesn't fit. Why don't you pay as much or maybe slightly more and get a bespoke suit made to your tastes? So because the sleeves need lengthening, he should go bespoke? Also, he probably didn't pay retail for the RLBL and Polo suits. Even if he did, bespoke in NYC is a hell of a lot more than the retail prices of those suits.
