I just bought these chinos from BR. They are a boyfriend fit. I sized up for extra slouch.

I've never worn anything that's a boyfriend fit before. I looked at my back view in the mirror, and the rear end looks OK, but the thighs and calves are really wrinkly in the back. I see that the pics online with the models show some wrinkling in the back too but only about half as much as I have. I assume it's from sizing up. Is a lot of wrinkling OK, or does that make the pants look sloppy?

I'm sorry that I can't post a picture...I have no camera.
