My pants in progress have a few nice details (sorry can’t find an image on line of the pants) including: a wide, lined waistband with mock-welt pocket inset into the waistband, a two piece back to the waist band that splits with a curved back and back tab and some topstitching.

Man, I think I did the welt 4 times last night.  I actually recut the whole waistband after the first dismal effort putting in the welts upside down.  

I am not happy with the final result but comfort myself in knowing I rarely be tuck in my tops, so the fancy waistband is probably irrelevant.
