I did change a lot of things.
First because I felt it was too small and tight, so I used a larger needle (6US), I CO 60, increase 40.

Then I knit only 46 rows because I panicked I was not going to have enough yarn (but I think I would have).

At the en of the legs I decrease like this: k2, k2tog.

The rest is the same, I’m pretty happy on how they turn out.
