I just picked up a pair of Zegna light weight wool pants I had tailored by Saks' in house tailor. When I put the pants on, I found a few feet of "cotton ribbon" in the pocket. I recall somebody on SF discussing attaching such a ribbon to the inside of cuffs to protect the bottom of the pants. Should Saks' tailor done this on his own? Is there a proper way to affix these cuff protectors?
