I typically buy clothing off the rack, but recently had a sportcoat MTM. The armholes seem to be cut differently than anything I wear in that they feel like they are higher than what I've had before, which gives me somewhat the feeling of the sportcoat being too small. However, the shoulders, waist, etc show no pulling and the jacket actually seems to make me look 10 lbs lighter. Are those of us used to off-the-rack jackets used to sloppy fit therefore does some MTM or even bespoke feel differently at first? I'm trying to assess how I know when a jacket does not fit properly due to how high the armholes hit under my arms. Thanks for any feedback.
