Junior size clothes are cut slightly smaller than misses or women's size clothing, which means that they usually appeal to teens, who have smaller body frames. They may also come in styles that seem "younger." Still, anyone can wear junior size pants as long as you know what size to get. Junior sizes come in odd numbers, while misses and women's come in even numbers. Get the correct fit by taking your measurements and comparing them to the brand that you want to purchase.
Wrap the tape measure around your natural waist. This should be a few inches above your belly button, where your waist naturally creases as you bend to the side. Write down the number in inches.
Take your hip measurement by wrapping the tape measure around the fullest part of your hips.
Compare your measurements to the sizing chart for the brand of pants you wish to buy. Sizing can vary between brands, so it's essential to check the sizing chart before you buy, especially if you are purchasing online and won't be able to try the pants on.
