I have a SWK Nightstalker that was too long. My lovely wife who is an accomplished seamstress, she specializes in bridals and such as that, hemmed it for me. Because of the pleats and not wanting the stitching to show, she hemmed it by hand. The only way I know it was hemmed is that it is almost two inches shorter now.

When you take it to someone, make sure they understand what you want. If it is machine hemmed, the stitching may be too tight and pucker the edges of the pleats. It may cost a little more to have the hemming done by hand, but it is worth it. Any seamstress with even a little pride in her work would not want to let something out of the door that reflects badly upon her skill.
