Hmmm... I've been sewing down the pleats on my kilts so far, so I don't know about the hem letting out since I hem first then sew them....

Wait a sec... just figured it out as I typed that- if I put a thick waistband on it, I can move that up as the years go on. The waist will look a little bunchy halfway up, but that's what belts are for.
