Most of our (Marching Band) kilts, from 1991, are the ones with the black lining and the interfacing that covers the stitched section of the pleats. We have a few kilts that are slightly older, which have an ivory lining and two layers of interfacing, but only for the first 2 inches below the waist band. See pics.

I am a seamstress, but my specialty/job is wedding dresses. My feeling is that the full interfacing is nicer construction, but maybe there’s a reason for not extending the interfacing. Since I need to replace the lining, I wanted to ask whether I should replace the interfacing as long as I’m at it. Steve said there are better options for interfacing these days, so maybe members can chime in about what material to use as well.
