Hi, has anyone tried these trousers, I went instore today and brought 2 pair in size 12 short length, I normally am a size 10 in marks trousers but they were too tight on the waist, the length is perfect for flats I'm 5ft2, now looking at the reviews more than one say that they shrink after one wash, now I think should I change for the next length, although I would have to take them up as there's around a 5 inch difference,
