Also it really depends on the size.
Same cut in size 28 will be way over inch shorter in rise than size 38 etc.
Could be that your natural waist is wider in circumference than your hip. Or the trouser is too wide at the waistband. In this case you could have them tailored down a bit on both sides.I love the look of a high waisted trouser but i can’t get them to stay up there in practice, however high the rise!
