It depends what shoes you intend to wear, and also what topper, and what color.

I would say longer looks more sophisticated and these look awesome at a longer length (which is not always the case!).

The navy pair is the cutest and wears well both cuffed and not.
I would have liked to see the green pair uncuffed too.

Navy uncuffed: try with lighter sandals or little heel, a white tee and a navy belt.
