Question: what does it mean when you cuff your pants?
Answer: Basically, it is a folded edge at the hem at the bottom and it looks like a turned-up edge that it's added to the pant leg. Traditionally, a cuff is not cut but simply folded from excess fabric at the bottom hem. Because of that, if you will let out the cuffs, you could always create a longer pair of pants or trousers.
