Summarize this article in one sentence.
Cuffs are one of the easiest, most popular ways to pair skinny jeans with ankle boots. Fold the hem once, and then fold it over again to create a double cuff. The cuff should bring the lower edge of each jean leg just above your natural ankle, revealing a thin strip of skin between the boot and the jeans. Try to make it so that the visible strip of skin is around 1 inch (2.5 cm) wide. A small glimpse of skin can help lengthen the visual leg line, but too much visible skin can create a large block that makes your leg look shorter. A single cuff can create a bold block at the bottom of the jean, without revealing too much skin. Fold the hem up one time to make a cuff that’s 1–2 inches (2.5–5.1 cm) wide. Single cuffs are great for people who have long legs. If you have shorter legs, try to keep the cuff smaller than 1 inch (2.5 cm) to avoid making your leg look short. If you don't like the cuffed look, try folding the hems inward instead of outward. Tuck the hem inside of the leg of jeans until you create about 1 inch (2.5 cm) of space in between your jeans and your boots.  It's best to fold the jeans only one time for a hidden cuff. To keep the fold in place throughout the day, you can iron the new hem at the bottom of the pant leg. While it might seem tempting to tuck your jeans into the boots, doing so can actually make your legs look shorter. When your jeans are tucked, they can bunch around your ankles, making them look wide and disheveled. This is even true for skinny jeans, which tend to be tighter than straight-leg or bootcut. Even though they might fit into the top of the boots, you should cuff them to prevent bunching.

Summary:
Roll the hem of your jeans up 2 times to create a thin cuff. Cuff the hem of a pair of tight skinny jeans 1 time for a bolder look. Fold the hem inside of the jeans for a hidden cuff. Avoid tucking the hem into the boot.
