well the casual I am wearing dosen't fit a wider belt than that. And yes shortly after that picture was taken I pulled it up a litle higher. Keep in mind I have really short legs and a long torso so it might look a little lower.
When the belt loops are too small...no problem...you don't have to use them. Many don't use the loops and some kilts don't even have them.

There's no need to hike it up a lot...1 inch will do. About the legs/torso...a wider belt will also help solving this minor optical "problem"...the wider belt will make the kilt look less long. Also...when you see more legs (knee)...your legs will look longer...that's a nice bonus.

I was not saying you look bad...not at all...you guys look great!
