About to send in a MTM shirt for duplication with several measurement tweaks. I am raising the arm hole height by 15/16" on the fold. Is it better to speak in terms of total measurements or on the fold when providing measurement adjustments? The same goes for a pair of pants. I am reducing the knee from 16.5" to 15.5". Is it better to tell them 0.5" on the fold or 1" total? Many thanks!
