I need some advice on kilt alterations. I just received a brand new Royal Regiment of Scotland kilt that still has the basting stitches and was never issued. I have been waiting on it for a while, unfortunately when it got here today it is WAY too long. It fits me like a glove except for the drop being 27" and I wear a 23" drop.

Normally I would just have it hemmed up like I have done with all of my other kilts that were purchased too long, but this one has the military rolled box pleats instead of the knife pleats. I am not sure if a kilt with the military pleats can be hemmed up 4" without it affecting the pleats. Has anyone had any experience with this situation before? I don't want to ruin a brand new kilt experimenting.
