Solution: A Good Tailor
Don't cut off the extra length and at the same time lose the nice crisp hemline (marked by the recognizable yellow thread). "A good tailor should be able to preserve the original hem," says Guillermo Molina, owner of Guillermo Couture, in New York City.

With very long pants, your tailor may have to cut off a bit of fabric above the hemline and reattach the original hems (with barely noticeable blue thread that matches the denim), but the task can usually be achieved by folding a hem up accordion-style and sewing it in place, so the original finished seam is in plain view.
