Waistline (clothing)

Your waistline is where your body curves inward, right above your hips and below your ribs. When we talk about waistline in clothing, we mean the part of a piece of clothing that goes around this area. It’s usually where the pants, skirt, shorts or dress sits on your body. Imagine a belt that goes around your middle - that's your waistline! It's important to find the right waistline size for your body so your clothes fit comfortably and look great on you.
