Since a few have asked about hip padding, I've taken some pics of my technique.
I've taken 2 soft square foam pads purchased at "Linens and Things" usually used for seat cushions, (How appropriate! ) and rounded them out with a pair of scissors.
This is how they look under panty hose:

NORMALLY, I'd wear a hip shaper over the padding to hold things in place and smooth things out. A beige/skin colored panty works best, with some legging. But I've left that out to show how the padding wraps around and is shaped to add where needed.
And this is the finished result, also without the shaper panty:

You can still see the shape of the pads a little, depending on what you wear, this skirt shows every little seam and crease underneath...
