So I'm between a size 14 and 16 trousers and bought some size 16 today from Primary and OMG I can't even get them over my bum put me in a mad dash to get some more as I need them for work in the morning so I went to my local Asda got a size 16 and they fit but a bit tight round the bum I'm hoping they hold for tomorrow till I can find some more, what shops should I try that are true to size, thanks
