MiceElf re bums looking big.
My understanding is that a big bum is not desirable when it is viewed laterally, ie from behind, so that those of us who were blessed with wide childbearing hips are sadly predisposed to have a bum that looks big in anything.
But it is a desirable feature if your bum looks big antero-posteriorly, ie viewed from the side, and the website to which Grannylin posted the link even going so far as to imply that if you haven't got a big bum antero-posteriorly, you should avoid wearing jeans.
Hope that helps.
