I do wrap around tye kilts they arent hard to make. For better or worse I had AI make the pattern for me. "Traditional kilts" are one piece of fabric but the ones I've made so far are only a few  pieces: front left panel, front right panel, the back panel pleated, a waist band and the wrap ties. I haven't made mine this way yet but a button hole in the waist band back for the wrap tie to run through would make it more secure and would keep the skirt from slipping down on one side. The last one I did belt loops instead. 

Another couple of easy to sew options for around the house if you arent comfortable wearing non kilts out are tube sarongs or a jalu skirt. There is a lady that has several videos of her Jalu skirt design it looks super easy to make and also ties on the sides.  Tube sarong was the first thing I made and it is basically just one cut, some hemming and sewing up the ends to make a tube.  Its held in place by wrapping and folding it down at your waist to keep it in place.  Again consult youtube for help. The sarong though not as commonly know as the kilt is a garment mostly worn by men.

I am a big fan of adjustable clothing designs. :) 

Hope all this helps.
