I'd avoid using tartan ribbon for a couple reasons. First, it won't come even close to matching the sett size so aligning it would be impossible. Second, ribbon isn't as pliable as bias tape so you're more likely to end up with buckling in spots trying to make it work on the waist band. Bias tape has a large amount of give so it's easy to make it conform to the contours of the band.
