If you've ever bought a new suit or dress slacks you might have noticed some of the pockets are inaccessible, here's why. Following is a transcript of the video:

If you've ever bought a new suit or dress slacks, you've noticed some pockets are sewn shut. The reason for this is purely aesthetic.

Manufacturers want suits to retain their tailored look, but as people try the clothes on they can alter the fabric's shape. This is especially true with the pockets. Stuffing your hands inside can stretch them out. The result is a slightly dilapidated-looking suit. Sewing pockets shut keeps suits looking fresh.

You can remove the stitching yourself after buying it or keep it sewn shut to retain the crisp look.

There are also "pockets" that are purely decoration. If you remove the stitching from those you'll just end up with a hole. You can tell if your pocket is real by its stitching. Functional pockets are usually sewn shut with a single thread. If you cut it and tug, it should unravel easily. If the stitching is hard to remove, it's probably not a real pocket. Whatever suits you!
