This is a great silhouette. It looks comfortable but well tapered. Lately my trousers are range between 16 1/2 and 17" leg opening. Maybe 16" for more casual fabrics like cottons. I have an actual 37" waist and US10 shoes.
Of course, this is all totally subjective right on someone's height, build and aesthetic choices? Personally I run away from wide legs, which for me is like 10 1/2" They remind me of the fashion of jeans when I was in high school and sad looking frumpy business men on 34th street.
