Weeell, is it fatter than portly? I hear how their redefining the clothing sizes because women are getting bigger. So a UK size 12 will become what would have been considered a size 14 and so on...so a Rubenesque woman will reduce down a size so that she is only portly (or matronly maybe - but that suggests 'a certain age' as someone said). If you can't manage to lose weight, redefine the problem!
