Completely forget about how you wear trowsers when puting on a traditional kilt. They look really bad if worn down around the hips like pants. Hike it up a bit if needed. I had one of my traditionals made with extra rise... and I wear it just under the rib cage or about an inch above the navel. I like the bottom of my kilts to strike across the top of the knee caps.

most important... enjoy the experience!
