Pants size 42 and T-shirt size L

Used in summer, at the end, very little worn. Jeans, worn 3 times, fit well for L, maybe XL. Similar pants I have from COS where it says size 42. Original length. Color dirty gray, late. In the picture, the model is 177 cm tall. I am 161 cm and they are just below my ankles, almost to the ground.
