The MCXX is true to size. Initial cold soak, six months of occasional wear about twice a week and one cold wash, the waist has stretched by about 0.5 inches. As already mentioned by others, they are very slim. thanks for pics gazman, i just bought the last pair of 33 avaliable,. its a size up from i normally get, but i measured my favourite pair of jeans using the BiG and they came up to 16.5. After a intial hot soak, they should fit alright i hope.
