I'm like Toady, which is easier in that I have a waist about two sizes smaller than my hips/bum so I can wear a belt to help. For the opposite type figure I think the wide legged trousers, low rise ones, or skirts work best.
(I got a pair of trousers altered lately as the were enormous on my waist, and I have managed to rip the seam when pulling them down as my hips/bum are so much bigger than my waist so there's not enough material )
