They shrank in length, a lot.
These are cute pants, and they are comfortable. Not too small in the waist, but they shrank probably 2" after washing! Perhaps it is my imagination and I didn't realize how short they were pre-washing. Maybe they only shrank 1". They are pajama pants, so it's not too critical, I'll just wear socks. But I found this surprising and will not purchase the same pants again.
