I bought these in a UK size 20 which according to the description is a US 16. They are no way a UK 20. I normally wear jean size UK 18, these trousers would not even meet to close the zip.
Quality wise they seemed good, I liked that you can make them into crop trousers by rolling up as well as the shorts version that they advertise.
I probably would have gave five stars if the size was correct.
