Proper Cloth can make modifications from a J. Crew baseline if you like. Tweak the collar, sleeve, length or midsection width. We also just upgraded our system to get even slimmer cuts in the chest and waist. We're now doing chest widths as narrow as 19.5 inches. Midsection widths as narrow as 16 inches. Tighter fits have no rear-pleats. Are you able to get Hugo Boss-type fits on your altered or tailored shirts?
