Saw your comment on the blog post, and thought that I could best answer you here.

Picture #1: There is no sagging crotch fit on these red trousers, yet they are looser than "the '90s trouser fit". I prefer the looser look because it looks more boyish, on trend and modern to my eye.

Picture #2: The sagging part that you see here is caused by my pose - left leg out and resting on right leg.

I hope that makes sense!
