Leggings, on the other hand, have a place in any woman's wardrobe. It's more flattering and slimming than the extra thickness leggings would add under a skirt or dress, which is the only way some schools allow them to be worn. A pair of leggings should be able to be worn with a shoe, although they are most commonly seen over boots. In terms of attire, many schools have adopted a relaxed attitude toward leggings, so long as you aren't wearing one piece of clothing with several layers underneath (like a sweater or tunic). You may want to consider wearing something beneath the leggings to avoid flashing people. Some schools also allow for yoga pants to be worn by female students. These are usually a single piece of fabric that goes from the top of the thigh all the way down to the bottom of the leg. They can be gray, white, or black, but rarely come in colors other than these three. Yoga pants are often used as workout clothes and sometimes as casual pants. Yoga pants first became popular among young adults in the 1990s, but they are now seen on children as well. Schools that permit yoga pants to be worn by students feel that it is another form of exercise and helps keep kids active. There are also athletic shorts available for girls who wish to play sports.
