Slim Fit Wool Rich Chinos

I bought these trousers for my 6’4’’ son. He is tall and slim. I bought size 32/33, his normal size. They were far too small. I then went right up to 36/33. They still didn’t fit. There is definitely something wrong with the sizing. I went elsewhere, bought a 32/34 and they fit perfectly. I wasted so much time going back and forward ordering the different sizes. Not going impressed.

Nice light material but the design is so slim it's almost skinny-fit. Not such a bad thing in itself but it doesn't have any lining on the thighs so, I think because it's wool, the material stuck to my legs and didn't 'drape' properly. M&S should standardise their fits across their entire range - some 'slim fit' jeans I have tried on recently were a little baggy and these trousers are a lot slimmer yet also described as 'slim'.
