There is no debate about the most appropriate length for Leg warmers. 28-30 inches or so is the most appropriate length. What is puzzling is that the most common length in this category is about 18-20 inches. In actual use scenarios, 18-20" is only just enough to cover the calf. For taller people, 18" is not even enough to cover the entire calf, and yes, even when wearing them close to the skin, 20" is not long enough. Any idea of expanding the use of these leg warmers is impractical. For example, with leggings or even jeans, because any greater expansion would make these leg warmers even shorter and they would pretty much stay at the ankle and not really be LEG WARMERS.
If your leg warmers can be longer than 28", then they can rightfully cover your ankle to knee, and even if you wear them on the bottom of your feet, they are long enough to cover your calves, even if you are 6' tall. In just those two cases alone, they are two more different pairings than regular leg warmers. Not only that, but they can even be thigh high if you're not particularly tall, as many customer photos and feedback confirm.
Many pregnant women and elderly people like to sleep in these leg warmers because such people usually do not have good blood circulation and their legs or feet parts feel cold or even numb. They usually just like to wear them up to thigh height. These leg warmers are soft and thick, but not very thick. They are generally like a scarf, and if the feet still feel cold when sleeping in winter, then these leg warmers are able to help them stay warm without adding any extra burden, and they are really more comfortable than sleeping in pants or socks.
The right height makes many people like to walk around the house in them, with T-shirts, shirts or thin sweaters or any other clothes are very suitable. These leg warmers can be a perfect replacement for long pants if you are at home. leg warmers are not a burden on the waist or hips and are very easy to put on and take off, which is the biggest difference between them and long pants. If you need to switch between indoor and outdoor, then these leg warmers are the perfect match.
Yes, the best length for leg warmers is 28-30 inches, there is no doubt about it.
