I dealt with the same thing. I ended up just sort of finding my way to make it longer... without making the 1st row wider and ending up with a diaper.
What I did was this:
Starting with the outer/uppermost scale, count down to the 3rd scale down and add a scale off of that one. You now have 2 scales to hang a new one between. Keep working your way down and this will add scales and make the angle of the loin cloth steeper. You will have outer scales that have 2 rings through them and will curve inward but are stable enough.
It's difficult to describe. I'll try to find a picture of mine if you are totally lost.
