I've recently lost some weight so went off to buy new trousers. Fitting nicely into size 14s on my thighs/bum/hips but they all gape horribly at the back. I have very large thighs and bum, hips 14inches wider than waist so I suspect this is the problem. I've always had this problem at every size (I just don't wear trousers usually- but I'd really like to). Belts just seem to cause bunching at the back.
Does any brand make trousers for the hourglass/pear shaped woman? Is this something a seamstress could deal with?
